Pretty cool game. The sound effects added a lot to the experience. The visuals are pretty simple but gets the job done.
For the gameplay side, the glitch mechanics are pretty fun to discover. I actually just plays around with it at the start and discover the glitches need for the game. I wish there was like secret levels when you go the wrong way with the glitches. The boss fight is pretty easy and uninteresting, so I thought that could use some more work.
Other than that it's a very solid, polished entry though, good job!
