I'll try the Mummy Maze stage but damn what puts me off from playing it is that it's really tediously long just for the purpose of collecting 5k and reaching the end.
You don't really have to even try to get the 5000 coins.
On my first playthrough of the level I think I got close to 6000 coins. I've since replayed to get even more coins. I'm trying to see if it's possible to get OVER 9000. Haha
