Important multiplayer feature poll (Patreon)

I'm trying to replicate the multiplayer feature similar to what we had in the old Naked Fighter game. A feature I call "deferred multiplayer", when you and your foe don't need to be online simultaneously. Instead, the first player creates a "challenge" and uploads it to the server. The second player can "accept that challenge", download it, and put their own character to battle. In this mode, the first player who creates the challenge can't control their own character directly and totally relay on the "auto-battle" mode. BUT! But the second player (player who accepts the challenge), theoretically could control the character during the fight, because the fight happens on their computer. And the question is, do you think that we should allow manual control for a second player? Will it is fair if only one of the players can control the character manually, but the second player only has auto-battle?

Will be happy to hear your ideas!
