It needs to be harder to escape being absorbed by the blob

[Grifflez]

I strongly suggest putting a few more points into blob melee, and using shift+click and ctrl+click on the spread and attack buttons respectively.

It sounds cheesey but with a few points into melee you can smack people around and surround them, ideally slapping a thick membrane tile on top of which ever tile they start breaking to try and escape being surrounded and absorbed.
