I appreciate the originality that you have brought to the table. The concept is pretty unique. However, the overall game is not very fun to play. The resolution is a bit too small to be able to see without squinting, the controls are unintuitive and the difficulty curve is messed up. It's really tough for a beginner to just pick it up and play and the tutorial text doesn't help very much. For eg, I had to figure out myself that scrolling lengthens your arms and you can only grab on to a grass patch.
With that said, don't think that I commented to prove to you that your game is bad. Instead, I am trying to give honest feedback so that it might help you improve your games in the future. After all, that's what game jams are about, right?
In summary, the concept is unique but the execution and everything else is not very good. Have a nice day sir/madam :)
