I just finish it and it was really interesting!
I love the concept (orb revealing hidden stuff) but I also really liked the textures on the wall, it gives a little psychedelic feeling to this strange place. It's also impressive to have made this mush puzzle + a game ending with such little time (I almost felt off my chair when the camera moved in the end :p ) The text written on the wall is also a good idea, it accentuates the feeling of uneasiness. And the music and sound did its job too, maybe the background music was a bit too much like elevator music? But that's just my opinion. Overall it was a fun experience and I'm happy to have tried this game ^^
