Good question! I’m going to try to answer in fewer than 1250 characters to fit in under the ‘max post size’ cap. Hope I can get this right :)

In single player:
- In order to progress from one area of a level to the next, you need to eat enough objects to hit a ‘target size’ for the current area. A bit like PixelJunk Shooter or Katamari.
In co-op:
- To gain access to the next area only *one* of the player-Blobs needs to hit the target size.
- Players are allowed to pass objects around between one another (shrinking/growing as they lose/gain these objects).
- Once one of the Blobs hits the target size for an area, all of the player Blobs automatically level up to that same size.

As a result there are always enough objects to progress to the next area, and all players start each new area at (roughly) the same size.

We definitely don’t want to sacrifice SP level quality either: We’d rather make the main story levels work well in both SP & Co-op.
