The opening wasn't that special, but your thought process afterwards was much more helpful. Let me break down the highlights:
1. a4 a5 should not be your consideration. The 1. a4 move is silly by the opponent because it does not do anything to fight for the center of the chess board, nor does it develop a piece, nor does it facilitate castling. Your ...e5 move in response to 1. a4 is MUCH more solid because you are taking the center the opponent is letting you take for free. Here is an old (yet popular) blog post of mine on chess opening principles: https://www.chess.com/blog/KeSetoKaiba/opening-principles-again
After 2. b3? they continue letting you to grab central control. Better than 2...e4 was 2...d5 (pawn duo in the center) or 2...Nc6 (developing a piece while securing your center). The ...e4 move was okay, but it might help justify the opponent b3 move long-term because their Bishop may fianchetto to b2 and then have great range on the long diagonal aiming from b2 to g7 or h8. If your pawn was back on the e5 square, this would actually help you block the range of their Bishop.
Next (and this is the last moment of the game I'll comment on), I'd like to bring your attention to the position after 5...Nf6. Your pawn chain looks good (as you commented on) and it is aiming towards their kingside. However, this pawn chain mostly works here only because the opponent advanced their h-pawn and g-pawn when they should leave them close to their King and get castled. What I'm about to say is more intermediate to advanced, but when you have so many pawns on light-squares (e4 pawn chain to b7), then you have weak dark-squares because pawns only attack diagonally (same color complex they are on).
Here is a beginner friendly video where I explain square weaknesses slightly more. Square weaknesses are especially dangerous in front of your castled King, but they are weak everywhere on the chess board including your pawn chain here on the same color squares:
Square weaknesses also apply against players who push pawns way too often and this video of mine might help you with that:
^^ Won this game with a similar start as the Ware opening, but instead of a5 for my second move I went with e4.. can't seem to find anything anywhere that explains exactly what I did in this game but I think that I may have found a new gambit of some sort?? In particular, the pawn chain that I had went from e4 to b7 and my knight on f6 made the two front pawns very strong, and gave me a ton of space on the board. With that, we started to attack each other on the kingside and I think that the way I set up my pieces in this game gave me a huge advantage and may have set me up for a new type of gambit.. or at least I would like to say that, I just can't find anything that resembles the piece structure I had in this game. I guess all I'm asking is if I'm a chess genius or if what happened was just an anomaly lol.
