It's hard to say precisely what it is all about, but there are hints of parallel worlds and other metaphysical stuff.

The puzzles are tied together with a story as surreal as the visuals, and again like Braid it is delivered in the form of text blocks that pop up between chapters. After restarting one level a dozen times I shook my head and said, 'This is impossible!' I was wrong, of course, but I was completely stumped for a long time. While a few of the first set of puzzles left me scratching my head, I always managed to progress without too much difficulty, but the second set is absolutely fiendish at times. You might have solved that level easily the first time, but what if instead of one ball, there are five? What if you have to control two characters instead of one, and they have their own keys and exit doors that need to be collected and opened simultaneously? These are mirrored versions of the first 25, but with extra elements thrown in to make them even harder. Thankfully there is a time-rewind control, much like Braid's, so you don't have to re-do the entire level after a momentary slip.Īfter completing the first 25 levels, the game felt somewhat short and unsatisfying, so I was pleased to find that after the game's apparent ending there is a whole set of 25 new puzzles. Soon enough, though, you will be cursing as the key you need to unlock the door falls out into space or you get the exit unlocked only to find it is now blocked by a deadly ball. Next there are deadly balls that look like evil, leering faces that roll according to changing gravity and kill you with a touch.Įarly levels are fairly easy, gently introducing the player to new concepts and then ramping up the difficulty, then introducing another new concept and ramping further. First the doors are locked, meaning you need to get to the key before you can exit. It starts simply, tasking you to rotate room so the roughly-sketched protagonist can walk up the wall and across the ceiling, but gradually more and more elements are added to complicate matters. Simple room rotation is quickly complicated by deadly balls, inescapable vortexes, and more.
