Enjoyable game.
There is some hit detection and physics jank in the way. Thankfully they're not major things. Say, why is the action key away from the partner switch key? Why 'J' & 'P' instead of having the keys next to eachother like 'J' & 'K'? It's kind of an awkward configuration.
That aside, the read was quite pleasant, and the gameplay & concept is good! (without the aforementioned jank in the way) The art is well made too for a 3-day work. Though I wish the plant switches that Kaguya must activate stood out more.
I covered this game in my Touhou Game Jam showcase here!
