Thank you! Yes I spent quite a bit of time tuning the physics of the game. The fixed crates are actually circular colliders so you don't need to line up with them perfectly, if you just keep pushing they'll line up your crates for you. I used a proper physics engine for this game because I wanted the grouches to really be pushing down the walls of your fort and for that to feel scary. I completely agree sound effects would be great! Many thanks for playing!
