In that Game white did miss some good moves by Black, but again this was Romantic Bongcloud Chess, and therefore, they would often look at delaying moves as weak, so often even if it was not best, they would advance thier King anyway, plus In his version of the game, Opiumez notes that he commited a few Obvious Blunders.

Here is a recent game from the World Bongcloud Championship being held here on Chess.com, this is to show why one blunder can kill you
The Repitition Bongcloud!
1 e4 e5
2 Ke2 Ke7
3 Ke1 Ke8
4 Ke2 Ke7
5 Ke1 Ke8
Guranteed draw every time!
1.Kxe2!! Accelerated Bongcloud is by far the fastest way to develop the King!
1.Kxe2!! Accelerated Bongcloud is by far the fastest way to develop the King!
That is definitely a TN. How about 1.Kxf2!? eliminating the weak f2 pawn. Imagine how frustrated Black must be that White has prevented him from playing the usual sacrifice ...Bxf2+ to draw White's King out into the open?
no, it niether of them are considered strong against the Bongcloud Counter gambit, Kxe7!?
however these are from the Fairy variant and should never be attempted in serious Bongcloud Play.
A good gambit though exists within the 9. Kb5 Bongcloud, The South Detroit Gambit.
Probably, here is a game from the recent Marie-Jeane Tournoment, well played, and instructive
an OTB game that I played
oh and I glossed over the final combo, it is entirely sound
Conquistador, there is a market for your detailed research in chess, as well as your outright creativity! I was laughing for a good 10 minutes reading and rereading those names. You need to collect grandmaster games played since at least 1850 with all these lines and make an exhaustive study with annotations, and publish your work. Should take 15 minutes or so... 
Good news! It's estimated at only -0.67 for white. For me, the main question in Bongcloud is whether white can survive after that terrible blunder or penalty. I recall that in old games Bongcloud appeared sometimes as the penalty on the 2nd move when a player touches accidentally a piece that can not move!
It seems that the answer is positive for Bongcloud fans, white are able to recover slowly.
One line is missing the :Double retreat symetrical Variation
1.e4 e5 2.Ke2 Ke7 3.Ke1 Ke8 4.Ke2 Ke7 5.Ke1 Ke8
none of these line's are worth anything, ever try the gee where'd my pipe go gambit
For all you Bongcloud enthusiasts, you'll be pleased to know that at least one brave soul is championing this system. Maritoni seems to be playing it as white in all his games, at least as far back as I can see as a nonpremium member.
Here is his most recent win:
From the mid 1500s, we have Ruy Opiumez v. NN
considering many don't read the annotations, here is the intro to the game
Ruy Opiumez was a Spanish writer and Chess player, he is known to have played about two hundred games, and placed them in his book, El Axedrez de Bongcloudo. In it, he explained how the Now dying Spanish Bongcloud works, and develops its intracacies. This was opening is only famous for its part in game five of the Now Famous secred Match between Fischer and Karpov. Here is the example game given to us by Opiumez. Annotated by Miguel Najpot
