The inspiration for this game is pretty clear from the way it looks and plays. There's no problem with taking bits and pieces from pre-existing games (my game's movement is also very JS&B-y), but this is a bit too much.
Also, the dash didn't seem to work too well. I'd still hit the bullets even while dashing.
I'd love to see an expanded version of this, and I think there's great potential! It just needs a bit more of an unique twist to really get there.
