Wildfire is a game that you probably didn't play for the 5th Kajam, mainly because I completely failed to get it done in time.
The main reason for that was that I was busy working on a killer feature that I wanted to have available before people played (and forgot about) the game.
The new feature I've added to the game is the ability to create levels. This is pretty cool (IMHO) because it's adding "cloud saves" to a PICO-8 game. The way it's done is by exploiting the GPIO flags that were added to PICO-8 presumably to be able to control simple lights on your Raspberry Pi or similar. Since the data needed to store a level is pretty light, I save it in these GPIO controls, which can then be read by the HTML5 app serving the PICO-8 cart. The data is then stored on my own server via a REST interface.
This means that any level you create is available to play for all players via the "challenges" list! I can't wait to see what kind of crazy challenges will appear!
