Perfect short & sweet puzzle game for the jam. You got a lot of mileage out of the main mechanic and all the different ways you explored it.
I found a small oversight where you could push small crates to the edges of the pits that normally couldn't be jumped over normally and just make the jump.
All in all, the game is very well put-together, especially considering that you made it in 2 days as a solo dev with all original assets. You did a great job and the game was a blast to play!
