MTA3 - SMB3 Level Contest

[Mors]

Y'know, with all the free time I have with working on my own projects (which I may take some time off of because I get bored easily or don't know how to continue them), and me being on Summer Break for school, this might be something I can try joining. One question, though: is Gatete's "Super Leaf Engine" its own .exe file, or is it something that we have to import to Game Maker? That might be the big determining factor for me to join or not (assuming Game Maker is free, which I still forget from time to time).

There will be a custom editor, no GameMaker needed.
