Hi! I'm making a post to show off that the game runs great on Steam Deck! It's got controller support that works out the gate, renders fine and I think looks quite cute on it!
Several other players and reviewers have also commented that it seems to run fine for them on Steam Deck and haven't had any issue.
Anyway, this is unofficial, since official Steam deck verification happens separately by Steam staff.
See! See!! That's me!!! playing it and having a great time on the Steam Deck I got to test it out on.
