I'm weirdly proud of both hiders and seekers.
I think the box surfing is a modelling bug; how do they move a box while they're on top of it?
Having said that, all hail BLARG, the first seeker to climb a locked ramp next to a box.
The hiders never "learned" to imprison the seekers which highlights a misconception about natural selection. The process doesn't find the best solution, it randomly finds advantages and favours them.
