I love it all. Absolutely beautiful and brutal concept. Things get uncontrollably difficult after 4, though the music accompanying you will make it less draining...1 found this helpful
Great puzzle game, really gets your mind spinning. Has a lot of fascinating mechanics.1 found this helpful
I didn't particularly dislike this game, but it doesn't stand out as an exceptional puzzle game to me yet. The puzzles are fine and it's nice to look at, but the narrative is kind of on the nose and the game overall lacks the intrigue and finesse of some of the better puzzle games.
50% simultaneous multi-agent movement (made interesting by the left turn rule) and 50% madness.
My brain hurts, also the music gets a bit repetetive
Excellent puzzles: difficult, but easy to get an overview of so your time is spent solving and not deciphering what the puzzle is. The music loop gets old very fast, though.
