I don't know if this is an issue in the desktop build but in the web build I found the game lagging a lot during the larger bullet patterns which was a sight to behold lol, but the engine and gamefeel are all very impressive recreations of the Touhou feel and the art and designs are insanely funny and cute (love the Kermit in a floatie). The music also is spectacular. Very tight patterns, probably the most difficult in the jam out of the ones I've played thus far, but the leniency with continues was a smart choice. Lots of potential here, though I can't say I "felt" much of the unstable theming.
