the dolls should have something like heath, so like if they lose to much blood or stay underwater for too long, they're considered dead (they automaticly stabilize and when they die, they go limp.)
things that this game needs..
1. dolls with gore, a certain amount of blood, and to stabillize themselfs when they're "alive" and not stabillize themselfs when they are "dead"
2. The abillity for objects to catch fire (combust)
3. more weapons
4. Maybe a online battle mode were you could customize your doll and layout (weapons)?
