Unfortunate Events

Whilst working on a new feature for my game, my project files got corrupt. I have no idea how this happened and I tried reloading a back-up I made. Unfortunately those files are corrupt too, and looking at it, it was the Engine that broke it. I was forced to redownload the engine and load up the project again. But for some reason the project had been cleaned of my hard drive. I have now been forced to remake my game, meaning that it won't be a fully finished product, but a prototype or maybe half a game.
