Fantastic puzzle game. I think the only frustration comes from hard-locking yourself on a level you almost beat, and having to restart. That said, most of the levels are short enough where it doesn't feel too punishing, and feels really satisfying when you finally beat it. The last level has my head spinning (fititng!!!) so I'm going to have to skip that one, but I was able to get through the rest and greatly enjoyed it. The mechanic of not being able to jump out of the cog wheels until they're connected to something was genius, it really strengthens the puzzles in the game and makes you think very carefully about where you leave those cog wheels.
The sound effects, the visuals, the super cute hamster, all really well done and polished. Other than maybe being a bit short on levels and the levels not being "balanced" (some later ones are easier than earlier ones, etc.), I could be convinced this was it's own game in development vs. a week jam submission. Fantastic work!
