You guessed right... For some unknown reason, when exporting the project to HTML, Game Maker strangely messed up the depth layers and the instructions ended up behind the Gorilla, which wasn't the case moments before I compiled it on my Mac...
Thanks for the feedback, I'll try to pay more attention to that next time I try to export to HTML, lol.
LOL we definitely didn't steal the idea from Wario Ware and Dumb Ways to Die, we would never do that, hehe, thanks a lot!
