Mauricio Tollin recently contacted me about his new puzzle app game Blicke.
  It's one of those 'slide your man until it hits a wall' type games.  The objective is to get the colored blocks to their targets.

There are 72 levels and yes, a bunch of them are easy. However, a lot of them are quite challenging and very well designed. I'm impressed.  
High praise for this game: I solved all the levels.
