I think the game has an interesting mechanic, you can choose to solve the puzzles or skip them entirely. In the end, winning the game is mainly about cheesing the scores.
If you wanted to, you could complete the game in less than 10 minutes, even with solving most of the puzzles I barely got to an hour of gameplay (and that included playing the last chapter twice).
I don't really think that the game is worth the pricepoint of 10 bucks. I got it on humble for way cheaper and still don't feel like i got my money's worth.
