The more percentages, the easier it's to knock out a character out of the stage, and that's the main goal of every match. Each character can perform deadly combos that you'll discover by yourself during the game.
From time to time you'll notice new items that you can pick up and gain an edge in the battle. Use them wisely because they can also work against you! Your hero can move in all directions using W S A D (including a double jump W W), attack in melee range ( O ) and from a distance ( P ), block attacks ( I ), and finally grab and throw the opponents ( U ).
