My companion currently has not joined Itch yet, he did play your game and asked me to forward it ^^:
'RB'
The balance is a bit on the easy side, but that's not bad during a game-jam, as it gives everyone a chance to see the end (hi mooncat).
Artwise, relatively simple, but I liked the way the characters grow, and you can't go wrong with slowly scrolling upwards to reveal more of the background, that's always a classic.
The audio is a bit repetitive, but the game is short enough that this doesn't really get in the way.
Short and sweet.
