I had way too much fun with this game... Lullaby, rap, Miko's boat song, memes, friendly controls, forgiving with mistiming the jump and dashing mid-air. I did quite a lot of mistakes and it never punished me for it, which I then realized is extremely rare lately. I finished all 3 levels and will definitely play it again tomorrow. A fun 3D platformer game, it's been a while since I've experienced that. Also, the Tsunomaki Janken game was a surprise, but a welcome one.
One negative thing I noticed is that both the Janken and the background song play at the same time. How about (gradually) lowering the volume of the background song to around 10% when Janken is playing and when it is over (gradually) increase it again to the normal volume?
