I'm not sure I like that idea. It's the whole concept of "get in, grab everything, get out". I would like to see -slightly more toys overall, mind you.
I would also love a way to deal with the elves, but I know that kind of defeats the purpose. Maybe bonus points if you do it. Perhaps Santa is so upset that he will squish elves if he's chasing you while they're nearby? I don't know.
This might be chaotic, but what about if, when Santa drops in, the elves don't actually disappear, and the toys currently on the map stay (but no new ones spawn), and toys are worth extra points? This would let you swipe just a little bit more on your way out the door, assuming you could pull it off. I always thought it was weird that Santa showed up and suddenly the board is wiped clean.
That said, I realize that some of these tweaks are probably more headache than they're worth.
Also, I get the whole concept of keys (I don't mind the decreasing bonus), it's just that most of the time, it's not worthwhile to get all seven keys and get out, if it's only worth 750 points. That's why I suggested that bonus increase to 1000 points or so.
And if you take my "toys and elves don't clear" idea, then maybe if you somehow manage to grab up all the toys on the map that are left, a big, big bonus (after all, Santa's hanging around, constantly getting faster, so it might be the sort of holy grail of bonuses).
