Fun concept, I enjoyed it! I'd love to see more levels/mechanics added to this and just more gameplay time. The only minor things I would mention are (and this may be a user issue) it took me a while to realize I had to click on the levels to start them (I was spamming all the buttons on the keyboard and was getting approximately nowhere lol), and then the other two minor points are the music- it was a little loud in the map, I think (it sounded like it was peaking?), and then when you die and restart in a level, I would recommend having the music continue rather than restart; it felt a little jarring to have it fully restart when I died. All of those things are super minor though, and I do think the concept overall was well-done!
