Not bad but nothing spectacular. It is not earth-shatteringly bad, but also does not feel like a complete game when lined up with the other game jam games this time around.
Art is a delight to the eye, but the clashing UI riddled with rushed graphical errors and tile map warping does stand out. Immediately dropped into the game without any quick control scheme to show (which I know is a small criticism, but its huge for accessibility!) Love meter isn't explained, pause button is Enter key and not ESC, and there is no reason to stand around and shoot enemies when you can dash through to the larger red fairies to proceed, and constantly recontinue, and ignore any semblance of "health" as a mechanic. Even when picking Reimu, my partner is changing from Alice, Reimu, Kagerou when I die? Boss has collision, and just pushes you into a corner, where you can attack spam to victory. When I won, the game crashed :,) Ending splash arts very good.
I see the vision, just needs a lot of polish.
