Increasing combo length

this seems to be my biggest problem other than my mixups, can anybody giveme some
pointers, or a sy stem for combo making

Without any mention of the game or even what characters, you can’t expect any response to even be relevant, much less helpfull.

If its one of the big ones, so to the character specific forum sections for the character you want to play. Look over the bread and butter combos listed, and practice. You’ll get bored, and want to hop online to mash. If you do, you lose.

Step 1: Know your combos. <- This is practice mode.
Step 2: Know how to land your combos. <- This is half playing, half practice mode.

Trying to skip to step 2 without step 1 and you’ll continue to suck.
