hey!
So the game must be made in the timeframe.
You can however make a new project, and make the new variation there.
There will be a slight penalty. but it shouldnt knock you out of the running.
In the rules I permit use of prior tools, i.e. camera controller, movement scripts, audio etc...
So you can save time there.
If you make a new version it must be different by greater than 50%.
i.e. if I view both games, it should be noticeably different.
Sorry if its a bit ambiguous, I just want to be fair to the people who are making it from scratch.
Let me know if that makes sense!
