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.

was close to just stopping since I didnt know if I was doing any damage or not, but ended up finishing the game, dont know how this GP works exactly, nor how powerful the attacks are, but an interesting concept
I cant see my hitbox so I almost always got hit once but they dont do much damage, just enough to be low after beating the game, so balance is good, the song is decent but stays in complete silence after it ends, instead of looping, and didnt really notice anything about the story or the use of theme until I read the description, but overall its nice, there arent any problematic bugs or just in general, at least not noticable ones, so good job with that, perhaps adding some sort of dialogue, looping the song and those QoL features like boss hp and this would be really good! its already decent even without that
