Trippy. I wasn't sure at first that the [vgrz qhcyvpngvba jnf vagragvbany naq abg n oht], and it took me a while to figure out (by blind trial and error) that I could press C to crouch.
Is it supposed to end with [snyyvat bhg gur qbbe vagb n oyhr ibvq, nsgre jngrevat nyy gur cynagf]? (This game does not make it easy to distinguish [vagragvbany sebz oht]...)
