Hi there. Not sure if you have time to solve this now, but your game has a dependency on MSVCP120.dll, which does not come by default on Windows 10. I am not sure if this dependency is permissible or not. I believe this comes from using Visual Studio 2013. If you are able to compile your game with a newer version, such as 2015 or newer, there will instead be a dependency on ucrt.dll which does come with Windows 10. But you might however also have a dependency on vcruntime.dll, which again does not come by default, but if you can avoid exceptions and maybe some other stuff you might be able to avoid this dependency.
Edit: I see you ship the needed dlls with the game now and it runs for me now. Luckily upx compressed them enough for you to stay within the limit :D
