It's a nice game, well scoped for a jam. I didn't get too far into it as I'm not a huge fan of these types of puzzles, though I have two suggestions for improvement.
1. The holes provide no information on how much cable length I'll gain by reaching them. I need to do trial-and-error first instead of just thinking about the puzzle.
2. Make your animations skippable(including movement if possible). In the earlier levels especially, you can finish most levels within 10 seconds, and then I have to wait for the level transition animation. The movement and restart animations also take too much time imo.
