Optimize game

[Deleted user]

We need to improve the game's performance. This will be important for our spec requirements as well.

I can re-compress most of these textures into a more efficient format. Later textures added to the game are already correctly compressed.

We also need to look into occlusion culling as well as other ways to speed up the game's framerate. Load times are pretty long too. But I know this is easier said than done.

I'll go through when we're finished with major development and remove any unused game files remaining.
