Hi,

I am planning on making my submission using a prior game as a starting point. 

Am I allowed to make any of the following changes to the existing game before the start of the Jam, or should I make no modifications until the Jam starts?

Work I hoped to do before the Jam includes:

• Creating a copy of the game, and checking that the game still works in my Game Engine.
• Deleting assets that I think I will not need from the prior game.
• Importing and configuring new versions generic gameplay systems (e.g. Scene Transition Manager, Music/SFX Managers)

To be clear, I am not planning on making any modifications before the Jam such as adding assets and logic that are novel or unique.

Thanks!
