It's a pretty good game.
I love the animations, especially the background one moving and when the dots explode.
The game is in fact easier on mobile as my phone lagged, but it's not really a modern smartphone as it has 1 gigabyte of RAM and modern ones have like a few more of them, plus Unity has said to me that Unity WebGL is not supported on mobiles so it's their faults and Unity should be ashamed.
Anyway, the gameplay is satisfying and is about pressing circles (as someone who used to play osu! I like the mechanic of pressing circles).
I don't really like the music though so I will rate it lower, it's piano stuff from Sheet Music Bros youtube and I feel like something with more drums would be better for background music, still the music turns off after a while and there's like nature sound which I do enjoy (unless it was from outside)

So yeah, this will not be easy to top in the game jam and as for now I can see it on the top list.
