That was an awesome danmaku! I can easily see it as a standalone game, not just a game jam entry.
Thank you so much for adding continues! It took me 5 of them to complete Normal mode though T_T, yet the difficulty seems to be pretty well-balanced. And it is impressive how you did all of that in RPG Maker!
I think most of the patterns of bosses are easier than most of the levels, but maybe that's how it should be (I haven't played Touhou since Undefined Fantastic Object).
Visuals, music, and sounds are all nicely aligned, and raining washing machines made me laugh. Definitely one of my favourite games so far.
