After a3 weak week, I'm thinking of better times

This is my game using 1. a3, Anderssen's Opening. This week, I was revisiting this opening and i did really bad, so I went over this game to see what I did right a few months ago and what I did wrong this week. I use to play a3 regularly and got pretty good at it, but have focused on other openings and lost it. I feel this type of move is more my style, although, I understand the importance of central control and so on. Anyway...here it is!
