@jaf im way more curious about how it was implemented than i am about playing the game 

 @opal hart just 4d space projected down to 3 dimensions 

 @jaf no shit but like muh opengl and engine memes 

 @opal hart you just have an internal state that is 4d not 3d. that's it. 

 @jaf oh yeah just implement the thing got it 

 @opal hart use vec4 instead of vec3
