since it's only a half-height tile, would it be possible to have the game check that you are actually in two half-height tiles deep of water, thus completely immersed, before trying to drown you.
It gets kind of annoying, standing in my shallow bathtub or sink, knee-deep in water, and drowning from that. It was funny the first time, though.
