I’m trying to make something for 7DFPS, the 7 day FPS challenge. I’ve never made an FPS before, or a 3D game for that matter, so I came up with a concept for a game I can build almost entirely out of cubes to keep things easy. I start the player on a platform in space. There are other platforms in front of the player. As you start playing the platform underneath you starts crumbling. To stay alive you have to run forward, jumping from platform to platform, shooting enemies in your path.
