Benefits of the full version:
"Stunning new 3d-rendered graphics and hand-drawn splash screens!
Brand new Adventure Mode will challenge master adventurers! Defeat 15 of the most devious pyramids we could devise!
Save your high scores and upload them to the web to compete with players around the world!
Nearly 10,000 new mazes to try, including the all-new 10x10 puzzlers!"
If you need some deatiled information about Mummy Maze, I would recommend downloading the demo version onto your pc, and the readme file contains quite much information about this game.
Thanks
