This was awesome! I love the mechanic and your puzzles are really well designed.
The box on stage 3 has a right arrow on it but it can only be pushed up, it should be an up arrow? That confused me for a bit.
Other than that bit of confusion, I really enjoyed it. Managed to beat every stage. I love how the pits on both sides require you to really think about your movement. The box connection mechanic was super interesting and fit the theme really well. Great job :)
