That's up to you!
Few points for you to consider:
- Take a look at the past Game-like jam entries/winners. There's a wide variety
- A top winner is specifically chosen for their "creative twist" on the original!
- Nobody is going to stop or disqualify you for taking the game wherever you want.
With that said, I think it's worth taking inspiration from the original that's embedded/linked on the jam page. But you're free to do with that what you want 😁
TL;DR the jam is for you to learn and make what you want, above all else!
