Good watching Bowen play KISS

He makes it look easy. Very good player and easy to learn to play from his videos. Still demonstrates how shallow the code is. One thing I learnt was that the 2X and 3X are not really bonus multipliers earned in the game as the original KISS. You have to finish two songs for 2X and four songs for 4X etc etc.. Has inspired me to fire up my LE this evening
