Welcome to the 5th Alakajam! 9

Wan 1 year ago on 5th Alakajam!

The new Alakajam! is finally approaching and will start on February 22nd!

The goal of the event is simple: make a game, from scratch, in just a weekend. You can do this on your own, or in a team, you can be a seasoned pro or a total beginner. If you opt-in to the competition, you will be ranked against every other contestant!

Full schedule

Dates Phase Description
Feb. 8 Theme submission & voting You can submit theme ideas for the jam and vote for all other submissions.
Feb. 15 Theme shortlist Only the best 10 themes are kept. Rank them by order of preference in this final phase of theme voting.
Feb. 22
6:30pm UTC
Countdown stream DanaePlays and Aurel300 host an official stream on Twitch to launch the event!
Feb. 22
7pm UTC
 THE JAM!!!  Until Sunday 7pm UTC, make a game solo or as a team, and simply submit it before the deadline!
Feb. 25 Unranked jam If you want to go for a relaxed weekend - or need more time - you can create a game in the 72 hours of the unranked jam.
March 10 Results After two weeks during which all entrants are invited to play, rate and comment on other peoples games… The results are released and the winners crowned!


There are three divisions:

  • Solo, in which you make a whole game alone in 48 hours
  • Team, in which any number of persons can gather to make a game in 48 hours
  • Unranked, a more open division which grants about 72 hours to finish the game. Useful for those not interested in the competitive aspect of the event, want to work on an existing project of theirs, or simply did not finish their game in time.

See the full rules for the Alakajam.

How to enter

All you need to do is:

  1. Create an account on this website
  2. Publish your game before the deadline

A lot of participants also post an "I am in" blog post presenting themselves or their team before the event. Describe what tools and frameworks and engines you will use to create your awesome game! Which themes do you like? Let us and the community know!

If you can, feel free to spread the word about the jam - the more we are, the merrier! glhf ;)

Submit your game! 3

Wan 1 year ago on 3rd AKJ Tournament

In March will be held the 3rd AKJ Tournament, where the community is invited like last time to play & compete on existing jam games! The event will be run right after the end of the 5th Alakajam, around March 10th.

If you want to submit your own game to the event, follow this link :)

Ratings mode & bonus days for submissions 0

Wan 1 year ago on 6th Kajam

The 6th Kajam now has ratings open! You are free to play, review and rate these hyper-casual games according to how addictive you feel they are. Also, most of you are already aware but due to popular demand, there is a last minute change to allow 4 more days for submitting late entries. Here's the final schedule:

  • Submissions close: Thursday 31st January, 7pm UTC
  • Ratings close/Results out: Tuesday 5th February, 7pm UTC

We're not extending the ratings phase until the end of the week because… Guess what? It will be time for the 5th Alakajam already, with theme submissions opening on the following Friday :D

Congrats to everyone who already entered the jam, and good luck to those still polishing their work!

Rocket Jumper: random level generation? 4

Wan 1 year ago on 6th Kajam entry Rocket Jumper

I've been making good progress with my jumping game, with the core mechanic now mostly done (…although physics were harder than expected to set up).

The next steps will be to draw final art… and more importantly, balance the difficulty. That difficulty part is quite tricky, as a good level design should be able to avoid "impossible situations" where deaths are forced. How could we do that yet keep the game hard, and even make it get harder with time? I see two main approaches:

  1. Keep the levels procedurally generated, and do some clever coding to make level generation harder & harder without being unfair ;
  2. Use pre-made "level chunks" of various difficulties, that would be playtested by hand.

Solution 2 would be too time consuming & unexciting, not mentioning I'd need to playtest again from scratch if I decide to tweak physics constants… So yeah I'll stick with fully procedural levels. To quickly get something I can ship, I've wanted to avoid being too concerned about imperfect levels: a trick was to introduce an "oxygen management" mechanic. The way it helps with level design is that it lets players do (limited) air jumps, which means that even if there's a huge hole in the level it still leaves a chance to survive.

Now, for the ideal solution…

The main idea I've had for "100% solvable" level generation is to place an AI player below the screen, before rockets are even spawned, that "plays" exactly like the player would. It would randomly decide to swap sides & jump, the trick being that the AI also decides when it lands: When reaching one of the 3 "rocket lanes", he'd be able to trigger rocket generation. A rocket would then magically appear right where the AI is, so we're 100% sure that the game is playable :)

We could then adjust the difficulty in various ways:

  • Especially in early phases of the game, filling voids with some additional rockets would help make things easy and the "AI path" not too obvious
  • The AI could play with increasingly tight timing
  • The rockets could be made shorter, or positioned so that there's little margin for error

I'm not sure how widespread this technique of using an AI is, but it may be fun to try. To be continued…

Hyper-casual is the new casual! 2

Wan 1 year ago on 6th Kajam

UPDATE: Due to popular demand, submissions will remain open until the end of the month! That means 4 bonus days. We'll still open game ratings on January 27th. See you then :)

The theme of the January 2019 Kajam is Hyper-casual gaming. As usual, you'll have about one month to make a game exploring the topic, with submissions due for Sunday 27th! Will follow a week of ratings on how addictive your game is, with the results out on Sunday 3rd February.

About "hyper-casual" games

I discovered this new term pretty recently, thanks to Bitslap sharing an interesting article about the trend. We're interested here in a particular niche inside the world of mobile gaming. It's been years now since casual games have taken over the world of app stores, from match threes to strategy games to puzzles. But now, the idea behind "hyper"-casual is that there's a growing number of successful apps that are actually very small games, focused on a single simple mechanic.

The obvious examples would be Flappy Bird of course, or 2048. Both were made in 3 days or less. An older one would be Doodle Jump. There's been a lot of games like this now that have been successful, even commercially successful, while at the same time seeming like they did not take that much time to develop. Studios like Ketchapp have outright specialized in such games ; their recent success Stack is a good exemple.


It seems like the overall hyper-casual recipe is as follows:

  1. Rely on a very simple but fun mechanic
  2. Make it require lots of practice to master (either by getting timing and precision right, or by perfecting strategic decisions)
  3. Make the game infinite, having the player aim for a high score
  4. Balance the difficulty right (to avoid boring or frustrating the player)

While I can't promise you this will make your game a success, it's certainly a type of games worth exploring. For me it will be a nice change to finetune a simple gameplay rather than cramming as much features & contents I can in a limited time :)

Bonus: One Hour Game Jam meetup!

Because those games are super easy to prototype, let's try something special and join the One Hour Game Jam to get our games started! OHGJ is a weekly event, and completely informal (no prizes nor enforcing any rules, ie. it's ok to submit late, reuse existing art etc.) so it's perfect to get your Kajam entry started.

I'm proposing either of the next two events for us to gather and give a try at a hyper-casual game!

  • Saturday 5th January, 8pm UTC
  • Saturday 12th January, 8pm UTC

See you there maybe! And even if you don't, have fun making a minimal but addictive game!

My attempt at single-button gameplay 4

Wan 1 year ago on 6th Kajam

I have tried to think about any simple but fun and mobile-friendly mechanic I could find, and here's the result:

Story: It won't be told explicitly (except maybe through the game name), but I always need a story to get me engaged in my projects. Here, humanity is escaping Earth due to an imminent disaster. Thousands of rockets are launching into space, except you have been forgotten behind :D You had the brilliant idea to just hop on a launching rocket, so now let's just try to stay alive…

Gameplay: It's simply about staying on screen for as long as you can, by jumping between rockets that scroll at different speeds. Maybe you just you can't stick to the rockets correctly and are constantly sliding along them, forcing you to jump to something else before you fall off. Anyway the controls are just:

  1. Hold touch for the right time to jump on a neighbor rocket
  2. Tap to switch sides of the rocket you're on
  3. Use 1 & 2 to stay alive as long as you can

I aim to build this both for PC and Android. And will probably prototype this during a One Hour Game Jam.

Here is a victory stamp you can use anywhere to boast about your participation ;)

I could not make it in time!

If you didn't manage to submit your game in time, it's okay. After all the goal was to make us move our butts and try to release a project, and you joined the party.

  • If you have a playable build, feel free to link it to your entry so we can all playtest your game
  • If you still plan to release your game, feel free to do so and try to be a late winner!

We're leaving entry submissions open to any late entries for the time being.

Modular Hope progress 0

Wan 1 year ago on November Challenge 2018 entry Modular Hope

A quick update on my A.G. Hope update towards a sellable game (now renamed to Modular Hope).

I think I've spent roughly 8 hours on the game so far, and it's been mostly dedicated to rewriting the controls and physics for the game. What made things a bit slower is how I've been trying to take advantage of "data oriented programming" patterns that are making their way into Unity good practices.

I think I have a good base now for managing & structuring those modular spaceships, the current step being to implement docking on top of it. My first attempt hasn't been too great :P I attempted to optimize things by creating a single, large circle trigger on each room to detect other rooms within docking range… Except not only I have a little direction detection bug (see below!), but I just realized that in fact it wouldn't behave correctly in all cases. What I need to do is put a trigger on each of all 4 sides of the room.

To be continued…
