Hey there,
First impressions:
I don't like the background(the sides), it feels too strong for me. HOWEVER, I absolutely love the way content is positioned below the game, I think it fits really well and makes me want to read it.
BANGER music, good vibes. I personally don't like the game, because it's just not for me. That doesn't mean it's bad. I like the minimalistic vibe.
I did not find any bugs, except one visual problem. Once the game is over, if you show stats and then click settings, it overlaps. Check the screenshot below:

I Hope this helps.
Best of luck,
Remi
