Were In! We'll be using :
Game Engine: Unity
IDE: VisualStudio
Audio: Bosca Ceoil & Audacity
Art & Models: Photoshop,Ilustrator, & Kenney Asset Forge
Wish you all the best luck, see you a the end!
P.S. Is Kenney Asset Forge allowed anyways? We don't have a 3D artist so we kinda have to use it :(
Welcome to the Alakajam community and to the 3rd Alakajam!
In terms of using existing assets, or primitives in particular: here's my opinion.
Good luck and have fun!
