Unravel is a fantastic and very beautiful riddle-solving jump & run game. It features an extremely well done storyline, graphics, great gameplay and soundtrack. I can only recommend it.
FEZ is a very beautiful, multifaceted, tricky, creative, crazy fantastic puzzle skill game done by Polytron. Certainly one of the best games I have played so far .. and I’ve played quite a a few (in the past).
Limbo is a fantastic dark 2D sidescroller puzzle jump’n’run game developed by Playdead from Copenhagen. Certainly a recommendation, especially if you like dark stories.
