Gaming Does anyone know why this game exists and who made it?

So a long time ago when I was a kid, I wanted to play Mario games on the computer. I would browse around the internet and download fan-made Mario games and play them. Many of the games I downloaded were well known (Super Mario 63, Super Mario Forever, Etc), but there is one game that I still have. I have never seen it talked about and I was wondering if anyone knew about it. It's a multiplayer game that is splitscreen. The game would begin with the players picking characters, and then entering a warp pipe. Then they would pick a gamemode to play on. If you want to see it for yourself, check it out here:

Controls: First player, WASD, Second: Arrow Keys. Space: Change Music

There is also a button for pause but I don't remember it.

So anyway, I originally got the from this site called mariocity.com

This website either got taken down or revamped, because it looks nothing like I remember it. It was poorly made and had many links that led to absolutely nothing.

The game was created by "Chris Edenburg" (as said when launching the game), but I can't find anyone who has a connection with this game online.

The original description boasts that the game uses the "Wypsa Gier Engine". Does anyone know what this is?

I really wanna learn more about this game, because no one seems to know about it and I'm curious if there is more info on this.
