Really underrated game, hidden gem in my opinion! The music is nice, the controls are nice, gotta love shift z x layout for shmups. Very nice gameplay, intrigued by how the danger lvl works. Decided to try a run without using night slash and I gotta say I had a lot more fun than I was expecting! Felt like a Phantasmagoria game (which isn't a bad thing.)
It doesn't utilize the theme as much beyond just "bird char in game" and "flying," but beyond the detriments to the lack of further theme use and a story, it's a very nice game! Short and sweet.
