Unfortunately I don't enjoy block pushing games because I am too dumb to complete them quickly and if I have the patience to push through I don't have a rewarding feeling. It's more like "Finally, I can move on to the next level"
That said, I didn't play all the levels because, well, I don't like the genre and the puzzles became difficult pretty fast. I stopped one level after the level with two lights, one huge, the other tiny. But the visuals were awesome and clear in what they were conveying. The idea of pushing lights, which define your area of movement, around is extremely clever. The levels were interesting too and provided me with a challenge to overcome. Great game!
