surprisingly addictive
I think it would be nice to let players know that their beetles lose health after races too, and not just fights. That was unexpected. And I agree, the betting system is off- if you're taking into account the computer player's bet as well, again, a heads-up would be nice.
And at least there is a way to mute the music, but if you're going to have it in the game, shouldn't you give credit to Linkin Park? Strange choice for a beetle game.
