The presentation of your game is the strength. The pixel art looks so amazing, with lots of little details and love put in. I think that's where the most time was spend on.
As for gameplay, i mean it's very, very simple. And that's okay for a 48 hour game jam. But i would have liked to play more and especially more difficult levels. Maybe you should have played around a little more with the clothesline mechanic.
Very short and calm game. Nevertheless you did a very good submission. My respect on the art. Great work!
