Things are looking up now. The pink set doesn't look too bad (I wish they'd kept it pink), and little references like the lemming statue are great.
The missions mode has got me excited too, I can see it working very well.

EDIT: Something fairly pointless I've noticed...
The 100ton weight is set much higher!
