Yeah, weapons will put the game to an higher level! The difficulty will be to keep all balanced each others. The success key of this game is the simple but variegate control system... adding a kick/other command can blur that, ending confused in the melee of similar games .
Question time: what do you think about of theese 2 different kind of control methods?
1st idea: Spacebar to defend, LClick for vertical attack, RClick for horizontal.
2nd idea: RClick as usual, hold LClick and move mouse to slash the weapon.
