More explosives! Snake is broken because of the fact that he can make the entire stage a danger zone. You need to use more trip mines and C4 to block off certain areas, and use grenades to apply pressure and funnel them into your tilts. You seemed to be trying to win through close range combat. Snake doesn't have a bad close game by any means, but to be fully effective he needs things exploding around him constantly.
Anytime you have a free moment, you should be setting up explosives or pulling 'nades. A lot of times in the video, I saw you just standing there. Snake should never be doing that, he should always be working to set up traps and increase stage control.
Don't do the full three hit jab, they can shield between the hits. The first hit of the jab is a fantastic interrupt, but do it into Ftilt instead of the second and third hits of the jab.
You have a grab release on Wario into both a Nair and an Utilt that are guaranteed. You should take every opportunity you can to grab Wario and let him release. When he's below 130, release into Nair. Once he gets to around 125, release into Utilt for the guaranteed kill.
Edit: I just saw you do a grab release on him. Do it more! It's a great damage builder. Get as many grabs on him as you can.
I think you should practice your techchasing some. His responses to getting down thrown were pretty predictable, and you weren't getting regrabs or tilts out of your Dthrows. In different situations, people will react in certain ways to Snake dthrow. A couple of body lengths from the edge, they'll roll to the center. Right near the edge, they'll roll to the edge. In the middle, they'll roll away. On platforms, they'll do a get up attack. These are just tendencies, you need to observe every player you face and see how they tend to escape, and use their tendencies to punish them.
GRAB MORE! Snake's grab game is amazing. His back throw has a lot of range, and can force your opponent into an edgeguard position easily. His Dthrow is just plain broken what with all the techchasing you can do. Basically, grab, grab, and grab some more.
Finally, get the infinite replay length hack so you don't have to play with such a short time limit
Don't take the fact that it's all criticism as a bad thing. You're off to a great start with Snake, and these are some ways you can improve.
Sweaty hand johns @ failed mortar slides. I know about jab cancels -> grabs, i just dont feel comfortable doing them in a risk v reward sitatuation where ftilt just does too much damage to not be used
