Garry’s Mod is a sandbox mod for the Source Engine. Unlike normal games there aren't any predefined aims or goals. Players are given tools and are left to entertain themselves. The player is in a world where objects can be created and destroyed on demand. Where people can be created and destroyed with the click of a mouse. A world made for him. A world he made.
Just something that used to happen when I first downloaded Isaac.
I wanted to make a better version of this image, but this error hasn't happened again since.
Oh god, what.
Also, I think that's a bumpmap bug.
Well, whatever it is, it doesn't happen anymore.
