I think the game was beautiful and a nice platformer. Single player game was a tad dull perhaps since I could just move one first to the needed position and then the other, obviously there was the time though. I liked the idea of this game and for sure with some polishing would be very good!
Took me a while to understand the arrowDown blocks, but once I got it, it was quite genius! But might need a small tutorial if there would be more of these kind of (you should know it) elements.
