I beat the first two stages (ended with 351cr and 96 cr).
The game is fun. The music is nice,I like the limited bullet mechanic, and grazing for bullets is appropriate, the time limit for boss fights fits pretty well with it too. The game goes at the right speed to me, the 3 levels are very different, pretty much every sequences of the game is cool and the boss fights especially are quite interesting. The difficulty is exactly as I like it too.
That's a very cool game, thanks for sharing.
