A very fun game with many interesting elements to altering reality for platforming and puzzle solving such as making safes light and fluffy so you can pick them up, reversing time and many more fun and interesting little things to do!

I'd highly recommend it to anyone who is a fan of puzzle-platform games :)

Edit: The ability to alter the quantum mechanics of this game makes for a lot of interesting and fun mechanics that remind me very much of Portal and Portal 2. Altering the universe to fluffy to make things light or make things heavy and you have so many options and the later puzzles are real head-scratchers.
