Adem Kayirci has a long history of publishing interesting 'minimalist' puzzle app games. 'Minimalist' is used to mean: the rules & mechanisms will be explained/discovered as you play through the levels.
My favorite games from Adem: cohex and maze cube gravity. See links below.
Way of Looking: The object is to roll the red cube to the green spot. This is done be flattening the 3d situation to a 2D image. For each level, you will have to unflatten to 3D, then rotate the iamge to another perspective and then flatten again.
