Lovely puzzle platformer - visuals and soundtrack are really amazing. The songs, wow. Something about this game really reminds me of Celeste, I don't know if it's the way the character moves or the overall vibes.
Only one thing was a little unclear to me at first, and it's the smallest pet peeve, but I didn't notice right away that I could dash upwards (or even diagonally), so one of the levels really puzzled me until the Eureka moment came.
I'll also say that I really like the character controller, it feels very polished. Usually when I see abilities like wall kick/wall run in games I'm always afraid it'll be somewhat janky, but this one felt completely natural to me.
And at last but not least, the ending scene is cute as heck. Great job!
