Very interesting game and well made! I have to say I never play any myst game and I was somehow lost. The presentation is insane good with all the graphics and audio. Very nice!
Some findings I had: Navigating is hard, maybe some Arrow UI elements which are permanently visible. Camera movements/shakes. E.g. on the lift or if this eye talks to you. Maybe skip puzzle button for the noobs like me
Good job on this!
