I loved that claustrophobic atmosphere. That's interresting how the dithering changes everything, and makes you fell even more lost ! On my first play though, I had no clue what I could see... I thought that it was a weird sphere... But once i got used to it it was clear.
The few piano notes are great ! It gets a bit repetitive, though.
I wonder, is there and end ? Or... There is no end. Just getting lost ? If so, is it generated ?
