Kubos. comes from Abel Galvan.  It's a 3D maze game.  The orange block will travel until it hits a wall. The puzzle is solved when the red button is hit.
 There are 40 free levels and 40 paid ones.  I solved the free levels pretty quickly.  I struggled on level 34 (4th image). I particularly like the puzzles that have 2 orange blocks and 2 red buttons.

Good job Abel!
