Nice game. I liked the sound of the blaster+ timing it to the soundtrack. I liked the revolving gun makes it less spammable than most bullet hells, forcing me to play more strategically with my position, which I enjoyed. Also, I really liked the music. It got me in the flow state and wasn't annoying after 10 minutes.
However, I had a bug. I'm playing on a firefox browser on my Mac, and the game only covered one fourth of the game screen, no matter what I did to the window. Imagine four squares in a 2x2 formation, and the game was only in the top left square. However, my spaceship could fly to the other 3/4's of the screen, which made it easy to avoid the enemies and win.
