It's not time travelling. The virtual reality simply looks very 8-bit (just like how when you put on a Virtual Boy, the world around you was red and black).
The posts I did are done using CSS, which is a fair bit of coding.
The mission in Virturia is a rescue mission, and the kidnapped person was testing Virturia before he got kidnapped by a computer virus. (I wasn't going to say that much, but ah well.)
