The Insane Dragon Boss is almost impossible to beat, but u can beat it using the finesse, run backward(or upward) when the dragon was doing something, and than come back to continue atack it, altough long, it can did it though~
when the headphones loses is like when you started the 'Serious Mode', and yeah, actually this game should have more data when a race is finished, like the multlipier, max speed, av speed, and so on. After all, this's a good game. Fav' 5/5.
