This is one of the smartest puzzle games out there and it will definitely test your understanding of its logic in every way possible. It doesn't like to waste your time with repeating the same basic ideas that you already understand, but instead constantly introduces new approaches to the way things can be manipulated and then builds on the harder concepts in later levels. I have been stumped many times with only a few levels where I actually found it somewhat obtuse, but often it really is just outright clever. Definitely earns its place up there with some of the most ingenious puzzles alongside The Witness, Stephen Sausage Roll, The Talos Principle, and many others. Do yourself a favor and play it already.

Just a disclaimer: you can subtract about 25 hours off of my playtime since I restarted the game and left it open for long periods of time.
