Is it possible? I read that if you type something like "gravity = 500" in the console, it would change the gravity in that scene, but here I am wondering why it doesn't work for me.

Please, how can I change the gravity in game VIA the console?

that would be awesome

I think that was only possible in the map that was made containing a small circle and an orbiting moon under the use of LUA.

EDIT: It may have been the IRC Scene map actually.

The map you're thinking of is Orbit Lands. "gravity" is a variable its unique script uses, and so it's completely meaningless in any other map.

Also, there's a gravity constant for each scene. I don't know if you can change it in the middle of a game with the console, but you can mess around with the .ini if you like.

Actually, it is very possible to change gravity while playing.
... but only in scenes with a "gravity" variable.
