I defeated the boss, managed to save three stars during my last playthrough.
I like the presentation, how everything looks including the UI parts and the screen shaking, the sound effects fits too. I also like that any bullet will hit anything and the amount of control you have, not only directly cancelling enemy bullets with your own with is fun but also all the enemy manipulation as they target you, that's a big part of the game that you don't get when starting to play, you've really given tools to be able try to save the stars and if you fail then it's your fault.
Even if slow movement fits the game it is still a tiny bit too slow for my taste.
That's a cool entry, thanks for sharing.
