maybe go for a more realistic feel with this, have the water rise and lower it self acording to the irl tides (4 hours each way i believe) its not as noticeable but itl still leave its mark each time a player goes to the ocean.
i would also recommend you put in more documentation and notes as to what to alter if you want to change the times, which planes to affect etc etc. This is something I am interested in having on my map so il come back to this thread later on when i have time to fiddle none important map things
