Reduced 2-5's staff time to 25.5, but I can't get much lower than that. And "no unusual strats" doesn't tell me much, because there are a number of approaches (like, I only just realized you can go to the 0/9 gate right after Fortifying the first wood boxes and use Unmake/Remake to protect the others).
Changed the start of 2-8 slightly to make it a little less annoying, maybe? It's still tricky.
In 2-9, you were supposed to drop boxes on the left and right side of the spike pit so you could cross between the sides safely, then Fortify and throw the wood box on the left side over to the right, but I missed that you could just go in the right exit without putting any boxes down in the spike pit. So I added some spikes above the right exit to make this necessary.
2-10 was "meant" to end in a situation where the snake is down on the monster doors and you have to use the wood box to get over it. It's faster to just go through the door while the snake is pressing the switch, of course, but I didn't realize it was the more obvious solution. I changed that whole thing: now you have to either push an extra box to prevent the snake from dying, or be quick enough getting Brooke out that you can go through the door while the snake passes over the switch.
EDIT: I kind of hate doing the start of 2-9 for time trials so I simplified that too.
