During a match you will be either on attack or defense. Each "mode" gives you different options.

All attacks will build energy that allow you to do your big moves.

There are three types of basic attacks:

Light- Never countered but do little damage. These also build less energy

Medium - These do a medium amount of damage while granting a medium amount of energy

Heavy- These do the most damage but have the greatest chance of being countered

While on defense, tap anywhere to attempt to counter a big move. Remember though, you using the tap meter to try and counter as perfectly as possible.
