To keep things pithy, I really enjoyed the first half of the game, and found the second half to be unnecessarily frustrating due to poor game design. The inital puzzles you come across are challenging and very fun to solve, but as you move onto other areas the game requires you to teleport back and forth in order to progress. It becomes incredibly redundent as you swap between worlds dozens of times for the remainder of the puzzles, each time meaning a loading screen to stare at. If not for the constant swapping, I'd have had more fun.
