... you go to pick up something just out of reach, and hear "But there is nothing here!"
... you move barrels by running into them with your body.
... you can't pull said barrels.
... you are extremely near-sighted, but can see all around you.
... you hate all letters to death, and love symbols. The number zero... it depends on the circumstances.
... and, you brag to your friends how your game's 0.9.x is cooler than their favored 1.0 and 2.0 games. (no insult to this game, I actually favor DoomRL to anything else right now, which surprises me. I never imagined a shooter could be like this)
