One of the latest Unity games to work on my system. And it is a very good game. What version of Unity is being used? 5.4.1?
I'm glad it work for you, is it newer Unity versions that doesn't work? as far as I remember this is using version 5.5.3f1
Instead of a version issue, there is also the choice of rendering pipeline used by the game (urp, srp, built_in, hdrp) that can have a big impact on compatibility, my game use built-in I think, so the oldest one
