×I can only see three options for ending the room.
-Get a goblin following me so that it moves to (24,5) when I'm on the trapdoor one tile above.
-Somehow get to the final passage while a roach egg is still hatching at (25,6) so I have time to get to the tunnel before it dies on the hot tile.
-Somehow leave the roach queen alive and use some combination of well-timed spawning and moving through the tunnel to get her dead on the hot tile, while not having any of her spawn move onto the open yellow door.

The problem is, I can't see any actual way of doing any of these three things. The goblin method seems more plausible than either of the other two, but it doesn't seem that I can get the goblin behind the yellow door to follow me, and I can't see a safe way of getting the other goblin to follow me that also gets the roach queen into position.

I also tried moving a goblin onto the force arrow before manipulating the roach queen, but I couldn't see anything I could do there that didn't scare it onto the hot tile. Plus it would have walked onto there and died before I could reach the green door anyways.

So what am I missing? I know there are golems, but I can't see a way to use more than one.

×You need something to die on the hot tile as you stand on the hot tile.

×Namely, getting the goblin stuck on the corner of the passage it starts in to make it take more turns to reach you. Of course, you still have to time it with the roach queen's spawn cycle.

I also re-closed the yellow doors but I'm not sure if that actually slowed the goblin down at all.
