So I have started working back to back on some dreams and still on LBP3, and an interesting concept came to my head. a platformer level with "no" (not in a literal way) sponge materials.
What does it mean?
So the general idea, is that you start up in a lab room where there is a "sponge-no-run" (aka as what is grabbable) object that cannot be reached. Waiting for a little makes the professor place down an (I'll shorten sponge-no-run to S-N-R from here) S-N-R stair so you can reach that unreachable S-N-R from the start.
From there the level truly starts.
The naming is a wordplay "no-run" neuron. since sponges don't have those.
