Very cool.
Hey Jonas,
I liked your game a lot. I didn't get any "message" from it, but the exploration gameplay and subtle puzzles kept me engaged till the end. It's cool how exciting a simple change of color palette can be when colors are so restricted. You definitely explored multiple interesting elements of design here.
My one suggestion would be to experiment with different text being displayed in the game. The "i'm awake", "what will I become" theme definitely set an atmosphere, but I wonder how you could change the feeling of the game just be changing what was in those text boxes. Do you think you could give the game more of a Portal feeling if the lines were like the maze sinisterly talking to you ala GladOS? Or something else.
Anyways, I doubt you actually intended to get a message across, but were more just trying to illicit a specific feeling with the dialogue you chose, and I'd say it worked. But it'd be cool to try experimenting with other stuff.
