Well-made game, just like the first one. I have an theory on where the game is going. Spoiler below.
Did I mention spoiler?
SPOILER SPOILER SPOILER SPOILER
Theory: Mitchell got a visit from someone in the mirror world. (Righties can cross over to the real world. So far, none of them wanted to.). That rightie made a deal with Mitchell. Said rightie would kill Llehctim so that Mitchell could escape. Mitchell probably did clinically die for a minute. If Llehctim finds Mitchell, Mitchell would likely try to kill Llehctim.
