Hey, I really loved your game, it had some great ideas in it, and while it was very short, you could really see the potential. One thing is, the way it fits the theme feels kind of... cheaty. Anyway, I had a lot of fun playing it and the mechanic was pretty nice, especially the way the box allows you to get up some bits but also keeps you from entering some areas.
Also, I wanted to give you an update, that I have now uploaded a HTML5 version of my game at this stage. I haven't worried about polishing it, so it has some bugs in it, but now you have levels!! two... well, at least there are some. I hope you like it. I will keep updating the game as long as I feel like it. We'll see how long that is.
