This game is so cute! I just wanted to report that arrow key controls seemed a bit off. Left/right would consistently work but not up/down. Sometimes when starting the game it'd let me go up and down a few times and then it seems like they'd stop doing anything. Let me know if I'm doing something wrong!
Oops, maybe I should have explained the controls better!
The up and down arrows only work while you're holding the button to fly faster, they won't move Bel on their own :)
