I think you did a great job with the theme. This is very creative, I like the idea a lot, and I love the sprites for the trees.
One thing that crossed my mind for this jam was doing a reversed Lemmings but I just couldn't conceptualize it. This feels like that and is done quite successfully. I assume you considered this but the only criticism I have to offer is that I wish that I didn't have to sit and wait to turn back to the dirt block. There were a bunch of times that I tried to reposition and even though I had the solution I ultimately lost due to the time waste.
Overall good work on the puzzles for 48hrs I feel like these are pretty well fleshed out and have some real consideration put into them. Just maybe add a sit button in the future if you flesh this out into something larger.
