The main difficulty for white is to choose between Nxd5, exd5 and Bb5+ !?!

Cool, it seems that black has some counterplay after all! 
Clyde Nakamura already had a version of this gambit that is played from the White side. I don't remember what it is but I'm pretty sure (being up a tempo) it was more sound than the one from the Black side. It wouldn't have been played like this. I'm pretty sure all of those Gambits were double pawn sacrifices.
Ok I was remembering wrong... I was thinking of his "Hiva" gambits which were double pawn sacrifices and also had black and white versions named for gods, but yeah https://www.chessgames.com/perl/chessgame?gid=1610139 from the White side was just the Omega Gambit. The Omega Isis was already Clyde trying to do the same thing down a tempo with the Black pieces. Trying to make a version based on that up a tempo again with the White pieces again is... weird.

Thanks for your contribution

Honestly, I don't really know or care much about these strange Sicilian lines, I tend to go for "normal" theory. I think I've played the omega once or twice on accident though
Why show off or "invent" a "gambit that is clearly losing vs good play??
Why pretend to "invent" this opening which has already been played many times??

I suppose if white lazily plays nf3 it can transpose into the Nimzowitsch variation, even then you'd have to know all sorts of weird Nimzo lines. But again, if white just plays bc4 or something to hold onto the pawn black is just losing imo

A very trendy gambit at Super-GM level.
Just kidding, of course.
Somewhere around move 14 Black is totally lost, but it's a blitz game, after all.
LoL It was unexpected! 
I just checked and Clyde was last online here in 2019. He might probably be explain in the other recent thread that was about one of his actual gambits what the idea was supposed to be, less so in this thread which appears to be trying to make fun but yeah, no dice. Don't know what he's up to these days.

Hello Yigor, hello everyone 
I've just read your interesting gambit idea, which was also played by Nepo against Firouzja (although I think that was just a mouseslip). I think against the Closed Sicilian it makes sense to delay touching the d-pawn, so that you can play d7-d5 in one move, sometimes even d5-d4 to disturb the horsie on c3. Yesterday I wrote about it in my blog: https://www.chess.com/blog/CSB7/road-to-gm-titled-tuesday-2021-05-18-closed-sicilian-opening-up
I hope you'll find it useful and interesting.
