From what I could tell, your Game & Watch is already pretty good; you understand how to string his moves quite well. I'm generally quite bad fighting him, though; don't let your defeats of my own G&W get you your head. face someone who knows the matchup decently and that should give you some idea. Also I need to learn the tech timing for his D-Throw. :W
Just some tidbits about him (you probably know some of these)
-BAir hits five times in the air and has an extra hitbox when he hits the ground while the move is still out.
-DAir spikes in the initial frames.
-Dash Attacking people who are hanging on the ledge can stage spike them on the main three neutrals and other stages that have ledges like that.
I liked your use of FAir and UTilt. Learn the timing to properly release his Smashes, though; even if you trade hits, it's usually worth it.
