Very neat puzzle game, I saw it described as a mix of BoxBoy and Snakebird and I think that is a fair quick summary. Intended to give it a quick peak and aside from a break for dinner I pretty much played it straight through and made sure to go back and find the "extra" things.
The one thing I will note is that for whatever reason it taxes my PC a good bit to run it, I can literally hear my desktop "speed up" and run loud whenever the game browser window is up and loaded. Perhaps there is more complicated stuff going on in the background but it does not appear to be a game that should be that taxing.
