I played and enjoyed the one level that your game has to offer quite a bit, it's pretty well polished!
-I really like the art style! The characters are goofy and I like the glowing and crt effects. I think it all works together really well and the overall presentation is super clean. I just wish that poof that the enemies explode into was bigger, especially for the larger enemies.
-I like the rhythmic pacing to the level, it felt in sync with the music even in the points where I would die and get reset slightly off. The game and the music always felt in sync and I like that a lot!
-The movement did feel a little too floaty for me, but it was easy enough to get used to. I think making some slight adjustments to the speed the character jumps and falls would help a lot. In one of my runs, I was trying to hit every enemy but I was finding that I would fall too slowly to hit some of the more tightly packed enemies. If it were my decision, I would probably make the character jump and fall somewhere between 10%-15% ish faster, but that's just me.
-I did have trouble at the end of the level with it not showing my statistics. Everything was always 0. I was playing using the web version of the game, so I didn't try to see if it's the same way in the downloadable version.
Overall, I like where this is going so far and I'd be interested to see this game be more of what it already is.
