The game's style is really cool, it's simple but effective! It was also really quick to learn by playing naturally! Though one thing I do miss is a feeling of "Eureka" on the puzzles, I managed to complete most without getting stuck, I think I only did once where it said I had no more valid moves. Aside from that level, most others were easier to complete, I think you could explore more levels where there's a "catch" for going on direction A or B, so the player has to try again until he gets the "Eureka" feeling, that could add even more spice to the gameplay!
