Gravi is an intense puzzle-platformer that'll test your tolerance for pain. Fling yourself through terrorizing traps and manipulate gravity to swing towards victory. Death is guaranteed.
I have mixed feelings about Gravi. While entertaining, it is also very frustrating at some points. And while I like being challenged, the frustration came right out of the blue, where one level was very easy, followed by a level based primarily on blind luck, followed again by an easy level. The difficulty curve seemed to spike quite a lot. There were also a few abilities that I discovered early on which were either not explained very well, or that I wasn't supposed to know about yet.
That being said, it was pretty fun. The game, while difficult, offers plenty of checkpoints and a lot of levels to go through.
