To mah knowledge, there's only one MAJOR glitch where you go through walls.
This WAS my first project, but it was unshared for a good reason. I never shared it, so I updated it. It had terrible graphics, and one script that did literally nothing. So I fixed it! :D Move with the arrow keys. Press r to restart a level. Hold the down key at the beginning to shrink. This is my hardest game ever. All levels are possible, so don't tell me if there's one impossible. Some are harder than others.
