Pixel art is very nice. Music is charming!
Couple of suggestions in the bugfix phase, if you have time: it would be cool to add a sound effect for the "!" moment ... as a new player an extra bit of feedback might help me. Also, a little bit of narrative background, even just in the itch page, would be cool. I wasn't sure... am I the character on the left? Am I Dokibird?
Good work getting a nice-looking game submitted!
