And also, if the level is missing an tileset, it wouldn't crash whole game? It would be nice to have ingame error and if possible, cycle to next level with working tileset.

And also some game modes could use some extra options. To make pestillience (Or what ever, the zombie thingy) more interesting/tactic based, zombies could only walk and/or have short ranged instakilling weapon. Of course, the first zombie could be kind of "Super Zombie", with damage amplifier and running so he would get few kills early on.

I actually had few more ideas, but forgot them . . .

And also: I love /dom.
