Lego Scooby-Doo - Escape from haunted isle - Mummy in

This run saves about 10 seconds from the last WR using a "new" bug:
The wall-jump!
"New" is in quotation marks, as this bug has been known for a pretty long time now, but has never been used in a run.
You can perform it by jumping against a wall and pressing the jump button right as you hit the wall.
With some practice, this fairly precise input will let you jump a second time.
