A really cool shooter! Had fun with it, and really loved the artstyle and presentation.
The only thing I'd point out that detracts from the fun is the movement, it's a bit slow. Maybe it was just me, but the only viable strategy for dodging i could find is to continually move in a circle away from bullets, as doing any other movement I wouldn't be fast enough to avoid them. Could be improved with a faster speed, or with a dash (hey, maybe dashing also rerolls your weapon!).
Anyways, cool submission!
