Awesome puzzle! The idea is wonderful, the game is nice to play. Very good gameplay, beautiful design, nice music, all is perfect. It's seems simple at the start but it's become more complicated quickly with some blocks exactly where you don't want them! You have to study the map to find the good combination of moves and you're finally so satisfied to pass the level :) And the gate's concept in the bonus is so cool! We want more levels!
PS: I liked the humorous notes in the instructions :)
