Like the concept. Plays very smoothly. The connection with the theme is there, but could use some more depth. I noticed that after dashing through a couple of enemies, I would just keep shooting and moving ... and didn't dashed anymore.
Maybe add some countdown for when your extra 'layer' would disappear again - so you have to keep joining / dashing at some times.
For me it was now: dash 2-3 times, to have the upgraded guns ... and then keep on moving around and avoiding enemies and shoot.
But overall really nice submission!
(And for the record: first try: 64 sec, second try 74 sec)
