Nice work! I really liked your take on the theme, and the puzzles were well-designed.
The biggest issue I had was that the controls could use some work. The "W" key is overloaded to be climb/jump/walljump depending on context, and it often didn't do the expected thing. For example, jumping straight up from the floor would actually make you wall jump away from the wall if you were too close. This is made worse by the fact that jumps are a limited resource, so I had a lot of resets to that sort of thing. Ladders were also problematic. You can't really adjust upward on a ladder since "W" just makes you jump off it entirely (actually, just about any adjustment makes you just fall off the ladder). This made the whole experience more frustrating than it needed to be.
That said, I had fun playing, and would love to see a version with a little more polish on the controls.
