Take a gander at these two screens:
The gibs aren't super realistic (too many eyeballs, legs and whatnot) but they whip by fast enough that you don't even notice. I'm having fun. [grin] They even cash in for experience! The game also now makes a smug 'ding' noise when you get a new level.
Next up, monster AI. I think now that I have pathfinding this should be really rewarding.
Edit: The player can die now, and it goes through a mini-cinema before it allows you to respawn. This is pretty impressive because it shows I've decoupled my game logic from the player and so it's theoretically possible that I could extend this engine architecture in a future game to a multiplayer game! But that probably will never happen.
