To make the game more accessible to the current audience, I suggest adding support for multiple languages. In the old game, this was not possible. But Unity is clearly better at this.
I can help with text in multiple languages.
You can also remove the installation wizard, since the game can most likely run portable (it seems that this site thinks that the author hides bad code in the installer, but I checked it in Virustotal and a good antivirus: the files are safe).
