I thought the quality of the match was fine since I was able to see everything well - trust me when I say I've seen "bad" quality. x_x
I didn't say anything about the actual gameplay because I didn't know what you want me to talk about. But you said you wanted tips, so that I can do for you good sir.
You smashed too much. Kirby's smashes are weak, laggy, and don't lead into combos easily, so there's little point in using them. His B-air and U-air are about as strong as his smashes, and sometimes stronger if you're not sweetspotting the smashes, and the trajectory they send opponents is often more devestating (less of an arc and more horizontal).
Since Kirby's smashes are so unsatisfactory, your goal should be to consciously work on being hard to hit. I don't mean running around dodging as much as possible - that's just being evasive. What I mean is that you should play Kirby so that you don't let your guard down. Use attacks that have little lag and a good reach like the B-air. Yes, start with improving your B-air...
Make a conscious effort to hit with it at the very farthest you can reach with it to keep your opponent at a distance. Use it with various movement: approach with a B-air, strike with the B-air and then float away from the opponent, Full Jump straight up and B-air then use another B-air before touching the ground - there are lots of ways of using it.
Now your opponent will recognize what you are up to and start formulating ways of countering your strategies. Maybe he'll try Shield Grabbing. Maybe he'll slide away, roll, or side step. Maybe he'll try something completely unexpected. At this point, you'll want to recognize what
he's up to and counter that strategy with something of your own. When this happens, feel free to come back and ask us Kirby players for advice. (You'll know you're getting better at the game when you ask for advice on specific things instead of general "tips")
You'll notice I held off on answering what I thought of your Kirby. Why? Because I can either say "It was good" or "It was bad" or "It was meh", but that doesn't really help, now does it?
