No Issues, just Great Example!

When I was in college for my Bachelor degree 20 years ago in 2004 , for my final diploma project I have developed DOOM 4th Dimension game, very simple compare to this example, but still looks good, I wish I had this example back in 2004.
Here is gameplay of my DOOM 4D https://www.youtube.com/watch?v=G__Qhrms1fw

Spasibo!
