I like the asymmetric mechanics and the fact that every action consumes energy.
When playing the knight you are screwed once a rocket hits you. During one match i tried to keep floating through space without spending energy after i had been hit by a dragon's rocket, waiting for the dragon to waste its energy first, but didn't happen, what a clever tricky fella!
When playing the dragon the critical moment is the first seconds! Once the knight has reached you it is over!
in the beginning i was allowed to play dragon and knight, but after some matches i was only assigned knight every time, is this on purpose ?
