on the monster count,
the end fight is supposed to have continuously spawning monsters, so the hordespawner there is set to spawn 100 monsters.
unfortunately, the hordespawner adds the # of monsters to the kill tally right at the start of the map, so you end up with 100 extra monsters. to get around this and allow a player to get 100% kills, i made a second hordespawner that creates (up to) 100 'boss_death10' entities.
the great thing about boss_death10 is that not only does it add 1 to the kill score, it also fires it's triggers AND removes itself.
the way it works is that each monster spawned triggers a trigger_counter which is set to '100'. when you end the map, the normal monster spawner is killtargetted and the other spawner, that spawns 'boss_death10' is triggered to start. (this is why the monster count 'ticks' up after you win).
the boss_death10 spawner also targets the trigger_counter so when the counter hits 100, it killtargets the boss_death10 spawner.
there's a pretty big thematic change halfway through which i wanted to preserve as a surprise, so i deliberately didn't take any shots from anything passed the first section.
however, the first section is also where it is most strictly confined to 768x768 and i wasn't able to get good shots that didn't completely give away the entire area.
anyway, here's a couple that i used for cropping:
