Thanks for playing and the feedback! For the sequel I'll definitely make sure you won't have to remember stuff again (the easiest way is to just make a photo of with your phone assuming you have one) ;) There was a hint, the painting where the control panel is hidden behind is of a man browsing a bookshelf though I understand it's not a great hint because you get it before actually knowing you need it... I might still update the game to improve a few things :)
