HIGH BLOCK
ub+A
-Defensive gesture used to block high attacks.
 After a succesful block, you recover slightly faster then the opponent,
 enabling you to counter-attack them.

MID BLOCK
b+A
-Defensive gesture used to block mid attacks.
 After a succesful block, you recover slightly faster then the opponent,
 enabling you to counter-attack them.

LOW BLOCK
db+A
-Defensive gesture used to block low attacks.
 After a succesful block, you recover slightly faster then the opponent,
 enabling you to counter-attack them.

FRONT LEG LIFT
d+B
-Not an attack, you merely briefly lift up your front foot.
 This is to dodge the limb of incoming low attacks, like the Low Kick,
 but mostly the Spinning Sweep Kick, which can't be low-blocked.

===

SWIFT CROSS PUNCH
A neutral
-Probably your go-to move after blocking or evading an enemy's attack.
 One of the fastest attacks in your arsenal, but naturally it's very close-range.

CROUCHING LUNGE PUNCH
df+A
-With this attack you attack quite a distance and strike low.

STEP-IN MID LUNGE PUNCH
f+A
-Excellent range, but when blocked or whiffed,
 it leaves you wide open for a counter attack.

STEP-IN HIGH LUNGE PUNCH
uf+A
-Similar to the f+A move, but it strikes a bit higher.
 This also means the attack can be ducked.

JUMPING OVERHEAD PUNCH
u+A
-Best used to counter an incoming low attack you telegraphed coming.
 The player'll hop over the low attack and likely nail the enemy on the head.

===

FRONT KICK
B neutral
-Has a similar use to the A neutral attack, though it has slightly more range. Hits mid.

MID SIDE KICK
b+B
-Good to use after a succesful block, or can be used as a defensive, back-away poke.

SPINNING SWEEP KICK
db+B
-This attack will sweep an enemy off their feet and hard onto the mat.
 It's pretty slow to come out, so only use it to punish a medium-to-far away
 enemy's whiffed attack. This attack is so low it can't be low-blocked,
 so you have to jump-attack over it or simply back off fast enough.

LOW KICK
df+B
-A good medium-ranged low poke.

STEP-IN FRONT KICK
f+B
-Very offensive move, quite some range and likely to nail careless opponents. Hits mid.

HIGH ROUNDHOUSE KICK
uf+B
-Not many things are as satisfying as connecting a foot to the enemy's head.
 This move is not the safest in your arsenal and has a slow recovery, so use it wisely.

JUMPING SIDE KICK
u+B
-As with the u+A move, you can clear incoming low attacks with this leaping kick strike.
 Though this one simply ups the wow-factor a few notches.

SPINNING BACK HIGH KICK
ub+B
-Has a similar use to the uf+B move, but this one looks cooler and has a tad more range.
 If the attack is blocked or ducked, though, you're very likely to get punished for it.

STEP-IN SIDE KICK
f,f+B
-This move has the farthest range of all the attacks.
 If an opponent is goofing of at medium-far to far range, toss this out to suprise them.

===

STEP-IN KICK AND PUNCH COMBO
f+K, hold A
-If you need to clear a lot of ground and want to be offensive about it,
 pull out this Step-in Front Kick, Mid Lunge Punch chain.

===

TOMOE NAGE ATTEMPT
f+A+B
-If you're feeling adventurous, you can go for the classic kick toss throw.

Just some ideas for titles you could try:
Karate Champ: Second Bout
Karate Champ Reborn
Karate Champ Remastered

But honestly, Olympic Rematch sounds like a fine title.
