I like most of you get bored while waiting for my mist energy to fill up,so i take a break from spiral knights and i play this game :

it's really fun and addicting once you get the hang of it,and really a good timepass.
link me some other fun games or stuff that you guys do while waiting for your refill or when you get bored of SK.
While I wait for my mist to refill I play Real Life. It's quite fun actually.
Note: On a serious note, I play Lockdown, or outside of SK, tennis and ping pong when waiting.
