It is fun to fly with ultrasonic speed and fight for food. Also I'm curious:
1. Is there a win state?
2. The bigger you are the higher is the rate of fire and music speed?
Thanks for the comment!
1. No, at the moment it is only possible to play.
2. Upgrading the rate of fire and size depends on the number of pieces picked up, at first they are connected, but then the speed can be upgraded a little more than the size.
