I love the artwork! I really enjoyed using the cable to pull me around, great mechanic. Plugging in the lights was satisfying and I'm glad you're able to walk around the world afterwards.
My only suggestion would be to map the inputs to the arrow keys (in addition to WSAD) so that players have the choice to do both actions with one hand or two hands. I think doing everything with one hand made some of the jumps harder for me personally. Other than that, I think it's fantastic. Well done!
