I think the idea of a turn-based danmaku game is pretty cool, but I'm not sure I get that from this game. It kind of feels like the game stops every few seconds, forcing you to choose between two attacks that I can't really tell the difference between mechanically. Since we can't see Eternity's health, I kind of assumed Strawberry Cross was worse than Dream Bomb since it had a smaller range.
I also think some of the hit boxes were weird, there were many times I got hit and didnt think I should have. But it it was hard to tell if I was getting hit or not since the bullets kind of disappear when I got close, without a sound effect or anything. It was unclear when i was losing HP or gaining GP. I think you have the bones of a good system and some clarity would really help with that.
