My take on this is that the repetitiveness adds up to the feeling of the uncertainty that awaits and slowly builds up to some discovery that changes things but not dramatically, I mean you could have a bombastic display of colours and textures but by leaving it as simple as possible shows how in real life most of the things are repetitive until they aren't but then everything returns to some new normality. I really liked your message of "you cant outrun yourself" for an exploration game, it could mean that maybe the environment is not the problem because it the problem was within you all along.. very psychological. Good job overall!
