there are a couple of points where I put false walls/floors (the first and last levels) but other than that I did notice you can fall through floors if you fall fast enough. I think it has something to do with my movement script or the unity tileset feature.
if you're talking about the area with the hotdog, yeah you are supposed to be able to pass through the wall to get to it but the area itself has no purpose.
This is really good! the levels were all really creative but not too complex. I did find a bug on the ice rink level where the player sticks to the wall. other than that, the ui scaling is off in the non fullscreen mode, but the gameplay was great
