You will now be in a place with a lot of options. Choose "Single Play" for now. Then you should be able to choose the tutorial by clicking on the respective "dot", however, it doesn`t look much of a dot anyway. Finish the tutorial when you think you`re done, and then continue with the other missions. Once you finish with those, you should choose "Match Play". Now you are located in a lobby. Quite nice colors, heh? Anyway, click one of the tiny buttons over there, "Information".

You now have a popup where you see that you have a few stat points to distribute. You can distribute stats between STR, STA, DEX and WIL. Note this: what the stats influence in basic, they also influence in battle! STR (Strength) is for increasing ball speed while in basic and also increases the damage done with an offensive item. DEX (Dexterity) is basically your character`s speed in basic, but it also influences a lot of other things in battle. It increases the travelling speed of a flying objective item, decreases the time required to cast a spell, and also raises the number of meteors/homing souls. WIL influences the ball`s spin in basic, and raises the damage dealt if your opponent misses the ball and you were the one to hit the ball. Now, add to whichever you like depending on your playing style.
