Simple but good visuals.
Music can feel a bit repetitive after a while. Sound effects is a bit sparse.
Game lags quite a bit on web build around 3 minutes in. Not sure if it's some memory leak or not freeing the "comets" even when they are off screen?
Like others have said, then triangles being coupled to health and points and being rare make the game not as fun because you don't see score goes up.
Itch page could use some more polish. I also thought the theme interpretation is a little weak, it's basically only a "cosmetics" thing to provide justification for the ending lol. But it was funny XD
