Not bad... I like the Yoshi, and the combo video was okay. Nothing impressive and some obvious signs that your opponent wasn't very good, but good job putting in the effort to make a combo highlights vid.
Hey hey...I was doin my best!
Just two things that'll help you out real quick - firstly, never recover from low near the edge with Kirby. The top of his head is the most vulnerable spot on him when he's in the air and it's way to easy to knock you out of your jumps or up+b from this spot. If your opponent is on the stage, recovering like this is often suicide.
Secondly, in this game you should never be missing techs unless by choice. I noticed in the combo vid he got a lot of free hits in because you missed techs. In smash64 you can actually mash z before landing to tech, unlike melee where you have to time it better. While over time you won't be mashing it as you perfect your teching, at first it might help to mash so you don't get hit by silly things that shouldn't be hitting you if you teched properly.
Cheers to both players, and come play online at some point
