There should be grounds that teleport you somewhere..
one is blue and one is orange there could be a button
to activate the portals... the portals could be selected to
teleport mice or shamen or both....
here's a picture to give you the idea:

Edit:
[new idea]
The grounds then in contact with the cheese you cant place it there ( it dosen't let you put it on or next to the platform with the cheese or the cheese itself )

NO POINT OF FREAKING BRINGING THIS UP ITS OLD! - [EDIT] i thought it died.. v.v

We have portals for thet alredy and it will be very easy to get the first so /no support

:)

i see... but.
The grounds then in contact with the cheese you cant place it there ( it dosen't let you put it on or next to the platform with the cheese or the cheese itself ) plus you can't put portals on maps when your making one

I suppose this would go well with this - Topic-162781

You know, you can make portals by making the bouncyness 9999 on 2 grounds,

/half support
