A challenging concept with decent music and beautiful fanarts. Everything comes together as a rhythm game.
Although it seems kind of too hard even on easy as it requires a lot of memos and practices to get used to this ambidextrous setting, and the fact it has another lane that goes another way really messes directions key presses quickly.
Story-wise there isn't much to talk about. The good old moon story that everyone knows. But the chitchats between characters are fairly interactive and not much of a cliche. For the prologue, a slightly transparent textbox might help a bit in terms of visuals.
Arts are simply fantastic and cohesive as a jam game made in 3 days, rabbits with a lot of variants, many character portraits, buckets, hammers, mochis, and backgrounds, etc. Everything is well-shaded with expressive tweenings. It's very impressive how your artist managed to get all of these together in such a short time frame.
Overall I think it's a solid jam game with a fresh take on ambidextrous design, but the gameplay itself might be too challenging at the moment which I don't think I'll be playing it as often as I do with other rhythm games.
