Pretty decent game!
People should stop calling this a "rip-off" of another game, and rating it down because there is another game similar to it just made by a sligtly more experienced programmer. ALL games use mechanics and ideas that have been used before. Every FPS ever is a rip-off of Wolfenstein; does that mean that every one of them sucks?
We should look at this game for what it is: an amateur effort, but a successful one. It's pretty fun to play, and there are no game-breaking bugs. While the movement can feel a little sloppy at times, it's still better than 90% of what comes through the portal. I for one hope Torkvemada keeps programming.
