in this video, who was doing all that clicking, cuz that's really not needed to play snake anyways O_o
Now heres' my analysis
-You f-air spam too much and fast falling, let the animation do it's course. take advantage of a full hop b-air if you can.
-the f-tilt lock you did on the 3rd stock, it does not always work btw, in fact, it never does really...
-Keep in mind that snake is not like a marth or mk in that matter, so spamming moves is so un-needed. play more snake to understand the properties for his attacks, then you can take advantage of his frames
-Try to utilize his c4, do your best to time and lure
-Same case for the mine, on a fresh stock, if the opponent doesn't notice, lure him into the mine for extra damage
-you spammed grab too much, keep it to a minimum unless you're confident you're in range.
-try to do a few jab checks, that way you can follow up with a f-tilt, u-tilt, d-tilt, or grab
-learn to be patient if you can... power shield it
