Hmmm, as to the dopler effect I'm just not certain, far to technical for my knolidge I'm afraid.
claudio, I do agree another accessible football game might be good, however as Brian said, I'm not sure how you'd go about doing this in agm, particularly if you were planning to have the ability to switch betwene the different players during the game, dribble the ball etc.
Just on an informational point, there is one accessible football/socker game out at the moment, Super football from Vip gameszone http://vipgameszone.com/index.php
Of course, with only 1 available football game at the moment, there's certainly room for a good few more.
I'm glad you can find some wilderness type areas brian, Geography has never been one of my better subjects, so all I can really work out about Idaho is that it's not on the coast of the Us. also, I wasn't certain if you were in the middle of a city, or a lot of farmland which would make it slightly more difficult to find certain environments.
I'm glad you've found some sfx though. the Aligater is a good idea, ---- though you could just make it a stationary obstacle which you had to avoid running into while you dash about collecting the flies, or have a trigger reaction of the aligater waking up when you enter a particular area, and if your not out of that area after a given time, you end up as lunch.
While this would involve triggers and a timer, I don't think it'd be too hard to do with Agm.
