The character art is very nice, and I like the music! I think the gameplay needs a little more explanation, as I wasn't quite sure what to do, other than auto-shoot projectiles in the direction I last moved. The blue and red dots look like pickups, but they can't be collected from what I could tell. As others noted, the game crashes at the 3:00 mark.
Seems like a great start, especially the visuals and music. I hope you'll continue work on this game!
