Nice vertical shooter
I like the visuals and the overall polished where you have a full menu level select and and transitions, the sprites are pretty cool too, and its always a plus to see the game has controller support ^^
oh and i also like that you made it healthbar based instead of one hit kill.
Small issue i had is that i couldn't really get the rhytm down for the powered up shots, i've pull them off a few times but not regularly, and i feel some enemy combinations you put on the later levels are really super hard even when dodging with the jump(then again i'll admit i'm not that good at shmups :p)
Other than that this is very well made, had fun playing.
Good job :)
