Once I read the comments below about the missing bullet sprites, it became much more playable with some simply zig-zagging. I think the sideways leaning may have been a bit too strong, but you had a pretty straightforward core gameplay even with the missing sprite bug being considered. The knockback was also pretty strong, and attack swing/firing was a bit on the slow side. Overall you did a decent job, it just needed a bit more testing before submission to address the missing sprites.
