As a concept, I think this is really neat. As a game it does work, though it's not very puzzle how it is currently. Where the levels are harder, it's mainly from how many gears are being placed, or having to swap gears constantly.
The main thing I feel is truly "missing" while playing (rather than just "I'd have liked this") is a drawing-style gear placement. The longer levels especially feel made for one.
I completely agree with what you said. Right now the puzzles are either a strait line, or dark levels that are also almost a strait line. Can't say I'm proud of the puzzle aspect of the levels I made, I'd for sure have loved to have more time to create real puzzles that require a bit of reflexion, but too late to fix this now sadly.
The drawing-style placement you talk about is actually a feature I wanted to squeeze in right before the deadline, but I was taken for something else and it couldn't happen. This made the level 01-06 especially bothersome to play (and I even shortened it mind you!).
Thanks a lot for playing my game and leaving a review!
