That was pretty cool, i had to figure out controls, but once i did, it got good. Everything looks floaty, but controls really tight, which is good. I guess this is kind of a shmup/platformer mashup, which i've found pretty nice. Props for making EASY actually easier, so old men like me could get to the end.
Get some snazzy graphics, and you're golden, the controls are tight, and the game is basically all there.
It might feel better with a controller with a twin-stick setup, but i'm not sure.
Also, having to mash the button for a continuos fire and such a short timer on button hold is frustrating.
