Well, interesting game, I haven't been able to beat the AI yet :)
The in game "how to play" says nothing about that there is an "E" skill.
Furthermore "A" key would be more comfortable instead of "Q" - for me.
(and maybe more description about skills)
 "Supper Paddles Battle"){kind=icon}
 "Mini Arrows"){kind=icon}
 "numone"){kind=icon}
Thanks :)
