This game is fantastic, really cool concept and you do a lot of interesting things with it. With slightly more comfortable controls (space/enter/arrow keys made my hands cramped lol) I would have played many more levels of this.
Love the CRT filter presentation, the vertical format screen made me feel like it was an old arcade cabinet or something. The music stopped randomly for me around level 3 and never came back, and I managed to get trapped inside a wall once (that's what the reset key is for haha).
Overall this is a really cool and creative entry, great job
