What's with the 410 HP limit? This may cause some trouble in the future and I suggest it be raised to 420, an easy multiple of 30.

Also, the ability to add characters to the game and the actual process of characters being eliminated will eventually cause massive HP inflation to the point where it is impossible for any character to be knocked out of the game. Watch out for this. In the future we will need to either raise the HP limit or knock ever remaining character's HP down a set amount.
