Wonderful game! I really enjoyed it! The music is repetitive, but its fine, the art looks gorgeous.
The movement, the firing is nice. I really love the two endings. The first ending really easy to achieve, which I like. The good ending does require quite a bit of retries.
I love the fact that what made the bad ending easy, the rings around the thing, become a thing that makes the good ending harder, although that fact is a bit underutilized.
The lose a life - remove all bullets is a nice feature as well, it can be used tactically to lose a life but get into a spot where the things wont shoot at you.
And thats really my only problem with this. I get that general "spew bullets into the room and let the player dance around it" is a feature of bullet hell games, but there is more than that. A lot of little bullet spawners can be cheesed by the player. I would have loved to see some things that targeted the player. It felt a bit frustrating at the end, because it wasn't a wave based player targeted attack, it was just "spew a lot of bullets and call it a day" which was annoying. For example in Enter The Gungeon, a lot of enemies have focused attacks. They shoot at you. And then there are the few "spew a lot of random bullets and geometric shapes into the room and let the player dance around it" which is fine.
But apart from missing player targeted attacks and the game feeling a bit cheesable, I think its great. But there was a typo of space being "spase to continue"
