It's looking clean, though I'm not sure how to interpret the things in there (except for the trademark green-slash ghost).
I really appreciated the sound of slices and other feedback sounds and the minimalistic aesthetic is neat.
Though I didn't enjoy the gameplay much. To me the boss fight looked like a quickly made-up cluster of bullet patterns, and the level (with enemies) isn't interesting - it's just a straight line and the enemies are all in a line.
I featured this game in my Touhou Game Jam showcase video:
