Yeh, let me show you one of best flash games I played, Amorphous+.

Soo... you're a bald man in blue suit, equipped with huge knife, which is called "SplatMaster3000". You kill blobs. Would be cool, but it's not just about splatting innocent green glooples. Soo, the problems start when the blob has teeth as big as your forearm and wants to eat you. Or is built of acid, or burns, or contains sticky goo, or breaks rules of gravity, or replicates itself within some seconds...
Nobud knows that game already.
