Fight Karo controls

Open fightkaro.com, click the page so it has keyboard focus, then fight. On a phone, turn the device sideways. The touch stick sits on the left; Punch, Kick, Grab, and Super sit on the right.

PC keys

Hold the direction away from the opponent to block. Block is not its own key. Use jump to leave the ground and crouch for low attacks. Super (L or Space) only fires when the SHAKTI gauge is full.

Specials and combos

Forward is toward the opponent. The legend prints three specials and six strings. A gameplay video ends on a card that copies this same list and labels it as coming from the official site, so I count one publisher, not two.

Menu keys, still from that legend: tap a face to pick yourself, then the CPU; Left/Right changes your fighter and Up/Down changes the CPU; T cycles the stage; 1/2/3 sets Easy/Normal/Hard; Enter starts the fight.

SHAKTI

The gauge caps at 100. The launch build adds meter when you hit, when you are hit, and when you block. I am not printing the per-hit formula here because only that build states it. Spend a full gauge on L or Space. Each fighter has a named super; the names live on the character table.

If a key does nothing

These are general browser troubleshooting suggestions: click the game canvas first. Switch the keyboard to English so J, K, I, L are not swallowed by another input method. Leave fullscreen if Esc is opening the browser UI instead of pause. On a laptop, A/D or Left/Right move, while W/Up jumps and S/Down crouches; you do not need a numpad. There is no control-settings menu to reset.

Next: how a round works, or why there is no app.
