Cool game! I really admire that you were able to create most of the art and the music during the game jam while only working on your own.
I did feel that sometimes the "player" would be moving a little too slow for my liking so I think it would be nice if there was a 2x speed option to help pick up the pace a little. I also think that the concept couldn't been developed a bit more into interesting levels as the stages went on, since it started getting a little repetitive.
Overall, still a fun demo that I think has potential if you were to continue to develop it! :>
