Enjoyed the part of the game I played- only tried the first 9 levels. I found the game very polished, seeing it as a complete game. Enjoyed the idea, and felt it was executed well. Concepts and mechanics were introduced in a logical manner, allowing them to be easily worked out without being told, and level design was good. Difficulty scaled well, however I found myself stuck on level 9 (most likely due to my own inability to problems solve). All together, enjoyed the game, feeling it was extremely well put together, both in polish and design. Music was also engaging.
