[ReThink]

At first I was thinking of the deathtrap world of Limbo on steam ( platformer game ).  Random portals rather than static sounds like a lot of fun, as well as breakables and almost-invisibility.

There was an option for random cycling logic, basically each portal cycles through each destination randomly, but doesn't repeat until it cycles through everything at least once.

The traitor room also has a portal, however no portals lead to it; it can only be used as an exit.

The invisibility I made to cost a credit to use, and a cooldown of 60 seconds so T's can't be constantly invis. I also made it out of the way so it could be obvious if someone was using it.

I don't think i've heard of that game though.
