is there a way to change resolution without going inside the game since for me it just black screens after opening
There might be some way to do so inside of the games files - but I'll be honest, I don't have a solution offhand. best case scenario is that I produce future versions to have better download, to solve some scenarios (such as a DirectX11 version, as many are reporting problems with DX12). Apologies that the current version isn't running for you!
