Fun game, the idea was creative, the polish on art and music were really nice (the rooms looked very good especially), and it was cool to have a fairly complete little game. The ending got me real good, I wasn’t expecting that and gave me a genuine laugh.
I generally enjoyed the gameplay and didn’t mind the deaths at first cause bosses keep their HP loss, though by the final fight I started brute forcing with how bullet hell it gets combined with almost non-existent i-frames. It was tedious farming at the end without having read the tip though, so I would suggest adjusting the cost at the end (maybe after you’ve done it once) or making the info more obvious in game cause I didn’t know you could leave the corpses to loot later.
Nerissa’s fight felt really easy where you just stand in a certain spot under and can’t be hit by her while spamming attacks…until the sixteenth notes drop around you and you get comboed to the bottom of the room and just die. Unless I missed someting obvious, I would suggest a change in her battle style to be more engaging.
I also had a few minor comments, one is about the camera in the Shiori battle room scrolling down, it gets kinda weird on the second phase when Ceci spawns and immediately gets hit down to scroll the camera to outside the room. Second is while I think the inventory mainly being flavour text is fine, it feels like it should at least be some kind of pause screen since it locks all your controls anyways but you still can be attacked while it’s up.
Otherwise, great work, I really enjoyed the game!
