at current, the hull get stress damage till you reach 0% hull streangh, after that the game end with some kind of soul using the cam climbing and rotating up to the sky.
changing that with some kind of implusion effect would be nice, but could maybe hard to do.
easyer or additional could using the hull`s damage percent as some additional sound triggers. problem at current is, that you wont get any sound information sometimes (just the dept cranks which will play also without any hull prolem), that your hull is taking much stress and damage because youre to deep for its current % of strange, and this is not very realistic in my eyes, ithink if a hull is taking much stress and get structural damaged from that, it need fitting scary sounds, documenting that it could maybe breach in the next seconds.
but even more important are ramdom dept`s or better random hull strange
without a visual % hull indicator. If this visual hull streange/damage information is gone, you only have the extra scary sound information that something very bad is going on with your hull...
