There are some checks in place so you don't go through walls quite so often, but it doesn't fix it 100% of the time. The game is a little buggier than I usually make my games. You kinda have to close your eyes and pretend things are working. (Like you can go through walls, but please don't. And the blue force field thing you can probably push through it if you try hard enough and sometimes you can just walk around it).
Press G to reset is there if you get stuck or fall out of the world. It just spawns you back in the last room you cleared.
