Does that mean I can't write plugins specially for my game? I like to make plugins for formulas which I otherwise would do with script calls. I'm happy to share them as soon as I wrote them, but most if them would be useless for any other project.
Also for @arthurfalaschi
There is a slight miscommunication and to reclarify, we do allow custom assets to be reused. If you have an old project that has script calls or old custom plugins, you can reuse them! The key rule is that the actual game development (maps, events, coding, etc.) must start during the jam period.
