i spent the first two days on making a game that barely fit the limitation and when i realised that, i scraped the whole project and ended up making snake by following a tutorial, its probably the worst game i ever created
the project files are completely deleted but i can give you an idea,it was a top down 3d puzzle game with cel shaded graphics where you move objects to reach certain goals but moving those objects can get in your way afterwards so you have to back track to get the perfect solution,the game was too ambitious so even if i tried i wouldn't have completed it before the deadline
