I really enjoyed the idea of having the story partially told by the environment, the game space there may be small but it feels like there's a world there. The robot itself jumps a little way too high IMO, but the fact that there are so many checkpoints made the experience very pleasant regardless.
I ran into the respawn bug at the last level (because I accidentally pressed R instead of E), but I was curious and invested so I played the whole thing again to see the ending.
Good job!
