I tried running it (windows 8) but i got the error: "The procedure entry point SetThreadDescription could not be located in the dynamic link library C:/.../UnityPlayer.dll"
The game was made with Unity 6, and the player does need to meet Unity 6 requirements. Unfortunately, Windows 8 is not supported by Unity 6 anymore. You can check the requirements on the link below, under the category 'Unity Player' and ' Desktop'.

Thanks for the report though, it is something I should have added to the description and will do so.
