Great concept. It took a while till i fully got it, but the tutorial helped well.
Very well thought and to each other fitting purposes for each machine. I also like these soundeffects and that you even made an ingame-menu as well as these en-/disableable hints.
Only problem was, that there were some lacks (on quest 2 standalone one, especially noticable when moving/roating sidewards) and the buttons seemed to "fly" around a bit sometimes^^
But all in all great game.
