The version you see on the start screen is just an error. The correct version is the one you already downloaded
Right now, the game has no compatibility with phones, and a port could take a long time to arrive, because the game is still in development, and more importantly, in optimization phase
Good to know more optimisation is coming! I might have to stop playing this over the summer because I'm worried that my 6 year old PC will explode from the mix of a taxing game and the heat lmao.
