Liquids collisions make no sense. 1mm puddle shouldn't freely move the player and giant boxes around and easily throw them off a cliff.
It makes no sense what items can freely roll like they're perfectly spherical balls. Dropped a toolbox that was making me overweight and it just ROLLED AWAY.
Also, did I somehow miss the way to close water bottles or does this game actually take place in a universe where they never invented bottle caps? It makes no sense that I have to hunt down 250ml cups because this way I can make sure all my liquid containers stay full and I can use them one at a time.
