Cool game and I love the player cube. The animation and sound remind me of Pixar

The first dozen or so levels are pretty fun, but after some time it becomes much much more difficult to keep track of not only where YOU effect the doors, but where doors effect other doors; and often times just the slightest mistake can cost you half the level of progress.

I was very impressed by this game. It really works because it manages to go so far even though there isn't a lot of detail. I was expecting it to be easier for me on the first few levels, but it was pretty much hard from the start. What was also great was how the little white box moved around. It was really funny to see how it was jagging and contorting everywhere. It doesn't have much to do with the actual gameplay, but it's fun to look at.

I thought you could just go through the doors anytime you wanted. It is of course more complicated than that. You have to really experiment with this game, because you have to try everything to try to get ahead. It's amazing how something rather small can be so complicated. Even the background's cute.

Love it

One of the hardest puzzles I have played in a long time, and that's why I love it

Well made!

This game is really well-thought-out. Sophisticated level design + rules + easy controls = best puzzle ever :)
