I really enjoyed this game, from start to finish. Even if it was a bit pretentious.

The puzzles are entirely just lines you draw on surfaces, with mechanics being built on that basic premise, as with most puzzle games -- except the way it teaches you them without conventional tutorials is extremely creative and causes a lot of substantial "a-ha!" moments.

A lot of the mechanics really tie in perfectly with the themes around perspective, as well. I love how much this game is tailored around it. I won't spoil exactly how, but it had me impressed on multiple occasions. Pretentious, yes, but even if you don't like it, it shouldn't make the game any worse for you.
