Any Tip on how to fasten up the testing?
1. create a custom debug interface. A few people on here have created them for your games so either search the forum for a thread about it or post a new thread asking how to create one.
2. alternatively you can use the dev console (tab key on keyboard) while running your game through the VS editor. It will allow you to type in various commands to change scenes, condition values, values of values, add / remove items from inventory & so on. type help
when dev console is open & then press enter to find out more about the various available commands.
