You should shoot them an email or something and see if they'll let you make an update.

Hm, i tried it in GMS now... and i'm now getting errors for "external_define" and "external_call". Oh man, this is really ♥♥♥♥! THANK YOU YOYOGAMES FOR CHANGEING THE RUNNER DURING A COMPETITION!
If you want to play it visit www.innova-ware.com to get the windows-version, which still works.

That might do it, but it might be an error on my end. Whatever you do DO NOT UPDATE until the competition ends, or you will be disqualified. That would not be something I would be comfortable being responsible for! :)

First of all thanks for the nice comments :)
It's strange that it crashes now, i didn't change anything during your last comment.
Perhaps it'll work aggain when i upload it aggain? I will try it.

I can't seem to load it anymore. It crashes before the game starts.

Cool! I like the retro theme! Like playing in the arcade!

Rather good! Very retro, yet an original idea!
