Ooh, thanks Unknown Rabbit. I never thought of that!

...I do suppose you guys mean that you can cheat this puzzle by buttstomping inside the little gap?
If so, I've already fixed it! Only 99 people who downloaded TR2 before today will ever be able to cheat that puzzle ever again! Muhaha!

(Ehm... Unless there's another way?)

Edit: Ok, so I did figure correctly Thanks White Rabbit! (what's with all these Rabbits here?)
