Thank you for playing, friend! I want to improve performance across the board, but right now I'm trying to prioritize getting the game to Early Access.
I'm inclined to mention that Early Access prevents you from using Steam Next Fest so you'd best look around and see if they let pre-EA games apply for the Fest.
I was already in a Next Fest a couple years back, and you can only be in one Next Fest ever so the opportunity is forever lost to me now. Such is life.
