Awesome game with some really great juice. It's amazing how you have included multiple weapon types, allowing for more replayability. I think the power ups are cool and that the enemy variety is really good. It would be great if there was some kind of tutorial in the menus as I wasn't sure how to dash or switch weapons until going onto the game's page. Also some checkpoints would be nice (I'm not very good at it :)).
Overall, a really impressive, polished game with LOADS of potential!
