Hi! I have a couple questions. For one, is it allowed to have two main menu images – one a black screen with sprite line art, and the other the in-game CG? Also, can we have a different itch.io cover altogether that is not a sprite or in-game CG? Thank you!
Before answering the first question, the rule is that you can use a CG, but that means you can't use a sprite and a background anymore (since a CG is counted as background+character).
But yes even so you can still have a main menu solid background with lineart (from the CG) as a form of alternate menu, that specific graphics would also be within the rules. But it has to be the lineart from the CG, not a separate sprite line art made specifically for the menu.
The second question, the itch.io cover does not count for the jam limits, that can be anything.
