I think you have a very solid foundation for something very engaging here.
The graphics, the world you created, the character movement, it's all gives a nice feeling and is very well executed. And that music man, OMG, it's so freaking awesome when the beats drop.
I think where the game false a little short is on the variety of enemies and the lack of control over the weapons. I really wish I could change between my weapons, decide which one to use for crowed control and when to switch cause I'm running out of ammo. I also found myself wanting to be able to move more, like having a dash or a slide that would allow me to speed up or maybe get behind the enemies.
Like I said I think it's a very good base for something that could be so much more! So kudos on getting that to that level of polish on what you were able to jam in the month! I'd love to see a further release!
