Beautiful and Intensive
I loved Coma, and I love Skinny. I love how this game is open to as much interpretation as possible, making it a beautiful art piece. I myself see it as some kind of sequel to Coma, even if it truly isn't.
It's hard to tell what's real and not real in this world, which makes it all the more mysterious, and the presence of the Mama character adds a sense of fear into the atmosphere (especially for players who have had bad encounters with a woman uploaded into a computer, and briefly a potato). As to the theories of who Skinny may be, I'd say he is Pete's father, if only because the "dream" in the beginning portrayed Skinny in a paternal role, and the tombstone of Pete had an epigraph written by Pete's father, in first person no less. That's only my theory, but who knows?
The world of these games are vast and full of potential and I hope to see from you again soon. You have great artistic talent. Good job!
