The game in question I remember playing in the 90s but was an 70s or 80s game.
It is for 2 to 4 players where each player had one coloured token. The board was made up of a player in each corner with the aim to be the first to the top of a raised platform in the centre of the board.
I believe you had to do a lap of the board first and then start going up a platform of steps moving away from each player's corner and connecting at the top to a 1 inch square platform. The platform was raised about 15-20cm above the board with empty space underneath and the platform and steps were in white plastic.
I can't remember the name of it and is bugging me!
I will add a crude drawing when I get a chance. But it's neither Ludo nor Egyptian themed. I don't know the manufacturer although it could have been MB but I'm not sure.
Here is a very crude non turner winning drawing of it as requested:
