Awesome game - the visuals, sound, and gameplay are all fun and engaging - I especially like the VN section! I really enjoy the boss and its attack patterns, but the enemies get to be annoying. It feels unclear about what to do about them as they spawn instantly after being defeated, occasionally spawn in groups of 4, and often will even spawn just before and persist during the boss's attacks, which makes it awkward as I have to avoid their bullets which overlap and become near impossible to see, but more importantly, their fat bodies. I've tried a few different strategies such as hanging near the top while ignoring them until the boss begins an attack and then killing them, playing near the bottom and killing them before they have a chance to shoot me, ignoring them altogether, but each time they become the focus of the fight and keep me from enjoying the boss's fun and unique patterns.
That said, the core gameplay is polished, and the mechanics are well-made! The visuals and audio fit amazingly well with the game and its atmosphere, and the designs have such a personal touch to them. I thoroughly enjoyed the VN section, and I think I'd love to see a full game made in a way like this. Great work!
