Locking his Twitter account is probably the best decision he's ever made for himself and his studio. I can't imagine one podcast would've drove him to cancel Fez 2... my guess is likely on hiatus for awhile until he checks himself out mentally. And if he's not kidding, then oh well, I was never going to play his games anyway. Hopefully, he can get some help though if he actually is going through a mental breakdown. And of course, if he's trolling, then it's like the boy who cried wolf and he should be ignored and not waste anyone's time.
