Not sure how to "share" replays to be honest...
What you are describing is pretty much Game and Watch in a nutshell. He has very high ability to rack up a lot of damage but has difficulty landing kill moves (which can sometimes be frustrating when Game and Watch himself is the second lightest in the game). His kill moves are either not very powerful or very slow. Still, his smashes are perfectly safe on block if not a bit slow and his Up Smash has some invincibility making it a fantastic anti-air.
Let me give you this tip though: What Game and Watch lacks in raw kill power, he makes up for his ability to go far out from the stage and edgeguard while still being able to recover back again.
If your opponent tries to recover from below the stage, use Dair. That sounds crazy, but as long as you do it while above the stage while saving your second jump, you will be able to recover. This move is very hard to stop because of its disjointed range and most characters won't be able to weave backwards or airdodge without killing themselves.
If your opponent tries recovering from above the stage, then use your Up B as it has invincibility, travels very high, has a lingering hitbox, allows you to act afterwards, and allows you to parachute back to the stage. If you haven't used your second jump after using Up B, then after simply using any aerial, Game and Watch has the unique property to jump after his Up B.
Ofcourse, don't neglect your Fair, Nair, Bair, Uair, or Neutral B (Frying Pan) for edgeguarding either. They are all fantastic.
