The game has a very interesting concept, and could very well make for a series of complex, intricate puzzles, and could especially make for some open-ended puzzles with the right tools. However, as others have pointed out, mandating 15 seconds per statue can make things quite slow when you need statues. I would recommend there to be some kind of button prompt to at least speed up the timer, or maybe instantly make a statue. Also, perhaps this was a one-time thing, but when I left Level 1 after beating it, it did not save progress on the level select, thereby making me do it again. So that might be worth looking into as well.
