Go229 was a pipe dream. They made a couple but it was far from full-blown production.
Not to mention the small size and lack of vertical surface area, it would be a death trap.
Flying wings worked in WW2's time, but only if they had vertical surface area (such as long engine nacells acting as stabilizers on the Northrop design) but a completely tailless, small, flying wing design in 1945? They were dreaming. It would be many decades until fly-by-wire designs allowed this configuration to be feasible.
Note that the germans also had some Luft '46 designs with forward swept wings. If you recall the X-29 showed definitively these designs are too hard to control without computer fly-by-wire doing it for you.
Just because they made it doesn't mean it was an uber weapon. It wouldn't have changed the war one iota.
