Hello to another dev team with siblings! o/
The game's got a lot of charm! The dialogue was all very cutesy and I liked the sound effects a lot. I very much enjoyed the mechanics and I think your level design was good. There were a few tricky spots that I had to try a few times to get through.
I personally think this demo would have benefited from some enemies to jump on, but perhaps that's not what you were going for.
Great work, would love to have you try our game as well!
