Why I Should Have Made A Back-Up

I ran across a little game I made for my game design class: Retro Space. Unfortunately all that I have is the executable file. The artwork files and other assets are long gone. I made this little game using YoYo Game’s engine, GameMaker. I made all of the artwork (forgive me!). A few friends played it a bit. The music loop’s rights were purchased. It was fast and dirty making this game – I only had a month to make it while working a full time job and doing my regular weekly homework. Shortly after I had turned in my assignment, the HD on my laptop went out. Now that the assets are all gone, if I want to re-make the game properly I have to start from scratch.
