Wow... honestly, this is amazing!
Not only they stayed on each other the WHOLE level (sometime, they stay on each other for a certain period of time, but the WHOLE level is extremely rare). But they also got on top of each other RIGHT when the fifth fireball appeared on the screen, seeing only four fireballs in the beginning. From beginning to the end, NEVER going appart from each other... I never thought that would happen one day, honestly. That's pretty awesome, Dan!
I don't understand how the fifth fireball respawned on top of a fireball at the beginning and got stuck with this fireball right away... this blows my mind.
