There's an exploit where you can just jump up the side of a tall wall. Also it would be nice if I could tell the difference between the doors that end the level and the doors that take you to another part of the same level, and at least a subtle difference for the fake tiles that's right before the coffee in the second level, nothing else about the game indicated it was a troll game, so that was just mean. Other than that, I guess just mention the controls and keep up the good work.
