I agree with JasJas' comment, my main issue is it felt too tedious to get through a wave of enemies having to target them and only be able to hit them one by one. The upgrades are nice though and the more I played the less the spin to attack became an issue but it took so long to get there. I love the art and the sound, good job on that part. I do think it's a pretty interesting spin on the genre and I think, minus some pacing issues, you made a really cool game!
