I fucking hate you guys for recommending Waltz of the Wizard first. I spent like a half hour in the starting room just fucking around with everything, which was great fun, but then I went into the actual game and about had a heart attack. I was worried the sound wasn't loud enough, and then a guy came at me and laughed so loud I thought I was gonna really die.
Also, I killed the first guy by tossing an explosive barrel at him, because I didn't even realize there were weapons in the first room.
