The amount of time it would take to make a game so good is greater than the age of the Universe. – Gravitations - Player Made Missions Review

This is one helluva game. Probably the best game I've played in a long time. I find it to be even better than Plague Inc. and it's surely a ton better than the Angry Bird games. If you want a game that you can practically play until the cold and sad death of the Universe, Gravitations is for you. Bonus fact: this game is so good, the Universe itself took inspiration from it when making its Laws of Physics... I'm not even joking.
