Ours was, and is hahaha, a bug with the collisions of the map. If you try enough you can squeze out the map in one specific point. We coudn't resolve it because it depends on a plugin so...
Here is the game if you wanna check it out ! It's a roguelike with 8-bit style where you only have one stat, so all other values of the game are calculated based on this hahaha. Have fun!
