Hi,
Thinking that if you can't swim and the water level in the room that you're
standing is above your head, you should keep taking damage until you get your
head out of the water. At the moment you just take damage when moving between
rooms (although I think that the amount of damage taken should be reduced if
my suggestion is implemented). The damage taken while under water could
increase with time... however, most peeps can hold their breath for a few
seconds at least!
