I.D. PSX game help

The name of this PSX game has been haunting me now for a few weeks.  The concept was that you are in a square/cube and it would rotate to one of the other sides every now and then.  Also, on the ground there were switches to make the cube rotate but they were color coded.  I think the switch colors were red, yellow, green and blue which also matched with 4 players.  Since it was a PS1 game it was 4 players with a multitap.  I think the gameplay was a deathmatch style, but I'm not sure about that.  Anybody remember the name of this game?
