Really like this entry, nicely challenging, with a bunch of cool little additions to the genre (bonus pickups and dashes were neat).
Absolutely loved those chromatic aberration and fisheye effects, it gave a really solid retro arcade feel.
My only suggestion would be to give the dash a small little invulnerability frame, as I found myself getting a little swarmed with bullets, hoping to dash out the way only to get smacked in the face by a bullet I thought I was dashing past (oops!).
Good fun, lots of replayability, nice entry!
