Fantastic mini-game with a fun gameplay loop. Played through all the unlockable, and had quite a bit of fun with them. Lyra is a beast, and I'm impressed with what you were able to accomplish with it.
Nice touch with the enemies having better weapons, as you upgrade yourself
If you were to continue this in the future, I'd like to see a polished level, more powerups and more weapons.
I don't think it hit the theme very well, but regardless, I like what you were able to accomplish in the short amount of time.
