Is it possible to create a build(or version) of the game you are creating?
By that I mean a way to save all the current work as a back-up in case I screw something up? And should I screw it up, then be able to go back to this previous build ?
???
Yeah. You should read up on “version control”. Most popular version control solutions are SVN and GIT.
Although I’m personally much more familiar with SVN, GIT is a bit easier to set up since it doesn’t need a server.
When you work on your project with version control, you can ‘commit’ (save) changes you have made in your project to your version control repository. Later you can restore your project or any file in it to any state that you committed to the repository
