Well congratz on releasing the game! I tried it just now, it's very hard. I think it could be made to feel much more intuitive if you made the blasts on the right match up to the projectiles coming out.
It's confusing when you see a single blast at bottom, and two projectiles come from middle and top. If those were matching, I would be able to predict much more accurately where to move, and I think it as a player I would feel more in control and enjoy it much more.
It has some great potential for fun!
