I know you're aware of the mouse issue, but are you considering just making small copy/paste update for the sake of people playing in the future? The mouse sensitivity is so low that it takes 2 business days just to turn around, I gave up on playing because of it.
heyyy im so sorry, I will try to update with the mouse sens option but I think the project its broken because I changed game version to one more new and updated game engine but I think that broke everything, if it helps (not the best option I know) you can change mouse sensitivity on windows options and then changed to normally again.
