Super fun concept... this feels like it's meant to be on mobile. The gameplay loop is tight and satisfying, and the art/sound combo gives it a really polished feel. I think with a few more level variations or evolving challenges (like obstacles or enemy types), it could be seriously addictive. Definitely one of those "just one more try" games. Great job!
...and again the art is lovely ....i'm inspired to make my next game with similar art :)
