Hmm. Got more than my money's worth in puzzles. SO many!
Initially loved the concept but somewhere in the middle felt grueling and then became a little enjoyable again. If you love puzzling it will be worthwhile, if you want exploration not so much, very linear, just going from puzzle to puzzle basically. And word of warning it does have some tedium as it progresses. But also the new mechanics getting introduced over progression was pretty cool, one of which I would never have expected in a game that is a floating series of paths :D

I've had this game in my library for ages. How are you liking it?
