Great to see a well-executed orthodox STG here! Is it just me or are they surprisingly hard to find for a bullet hell jam?
RBG is nice looking, and overall fun to play with few quirks. The music is great on its own, even though I'd have loved it more with more integration with the level design. The early stages of the boss fight can be a little bit irritating with the boss moving around the stage much faster than I can possibly follow, making it hard to deal damage, but the later stages get better. Above all, it's amazing that you managed to put all those content together!
