So much stuff coming together in this! Groovy music and beautiful portraits are probably the biggest highlights for me. Nothing really struck me as missing, and the genre combinations of visual novel and boss stages was a good choice.
Gameplay does feel a little unpolished (most of my time devolved into sitting in the corner and button mashing) but I really like the idea of deflecting projectiles from a narrow road while a boss flies around shooting bullets. I wish I had any clever suggestions.
