Hi, I am considering buying this plugin but want to demo it first. Is it possible that you can make a built version(game.exe) available so that people can test it before buying?

The editor example project was also updated to contain a seperate map with the interface used in the shipping example

Pushed version 1.9 to the marketplace with 2 fixes.
