You can create a first build for the jam, but if you choose to continue it afterwards that's up to you!
Viewing post in Can the VN still be worked on AFTER the jam?
actually i have a follow up question
to establish context i want to release my first practice VN with the goal of gaining experience and i was recommended this jam by unagi.
the VN will indeed be a romance/drama...
but the initial chapters won't be that... because the main couple will only be introduced to each other on the very last scene at the end of the demo.
the initial chapters, which is the one i intend to submit to the jam is... not romance themed... it's drama. Very abusive and bloody drama. @w@
is that grounds for disqualification?
