Very nice. Probably the one thing I'd change is the fact that the goals of the game aren't terribly well defined - I mean how much junk do I have to catch before the level ends? And what do I do with the money, anyway?
I loved the previous parts but this is pretty boring, to tell you the truth.
It's more like Thing-Thing Arena 3 than Thing-Thing 4. The levels are small, you have no choice in what path you take, you end up in a corner with a hundred people coming at you every five minutes... You improved the graphics but dumbed down the gameplay.
