Entrances are randomized, phases have their own colors now, enemies can now suicide run into the fire, and enemies become "invisible" in the darkness. Fires are fixed and hand designed in though, I don't really know a good way to randomize them without sacrificing a lot of balance, but I think there's enough randomness to make it fun each time. Basically the farther you are into the game the less fires there are. Hopefully fun situations arise from not wanting enemies to run into the fire.
Now to do upgrades tonight...
Tomorrow I'll do a whack of things and be spending all day getting everything possible done. Really the main thing is just adding more enemies into the actual waves and enemy types.
