Great game. Really cool and inventive game play. Well done! 

I like the concept. I don't know if it was just me, but I couldn't move the cursor low enough to go small enough to go under one of the first blocks. Could also be a skill issue, haha

Very cool concept, the game is fun and easy to know what needs to be done. Unfortunately I couldn't play it on fullscreen, but not a big issue.

cool controls, i like the concept.
