Demons happened. There’s your plot. More specifically, they apparently happened to everyone except you, but the process still messed with your tv, so there’s nothing for it but to fight your way through them to some kind of solution.
Demons Happened is a curious blend of very rapid action faintly reminiscent of Hotline Miami, and an Abe’s Oddysee type of puzzle game. Such disparate genres don’t often blend as well as this, and I’m disappointed that it hasn’t got a bigger reception.
