Amazing little game! It is just a shame that the difficulty ramps so quickly, that it discourages me from just enjoying and experimenting with the mechanic. The first couple of levels should have just been.. rewarded for learning to control the machine.
Being asked to stack things right away in a very specific order-- over whelmed me, and I will admit cut my play session shorter than it otherwise would have been!
It would have been fun if you just rolled forward and moved a few things, talked to a few npcs--- learned more about Mr. Strange!
That's just my 2 cents! :D
Impressive game overall..
