; The Stone Ship Puzzles
; by deater (Vince Weaver) <vince@deater.net>
; at start, no electricity
; all lights on umbrella off
; tunnels dark and flooded
; steps to cabin are flooded, lights off past airlock, can't
; touch book
; lighthouse is flooded
; lights are always on in red/blue rooms
; umbrella pump -- only one can be on, touching twice toggles
; #1 drains main cabin
; #2 drains tunnels
; #3 drain the elevator room
; treasure chest
; 1st drain tower room
; 2nd go down, open tap, let water drain
; 3rd close tap
; 4th raise water again
; 5th click on chained key which will unlock chest
; 6th click on key in chest which will get picked up
; 7th open trapdoor. animation. lock and key fall to
; floor down below
; you can still pick up the key down there
; in game if you leave the lighthouse
; while you have the key, the key ends up on the floor
; down below
; charged battery turns on lights in cabin/tunnels
; charge runs down over time
; compass rose puzzle
; press wrong one and lights go out (all energy to zero)
; also siren plays
; blue light at end of corridor
; press right one, lights in the cabin go on
; also light outside the compass window
; lighthouse backgrounds
; water, no trunk, hatch closed
; water, no trunk, hatch open
; water, trunk, hatch closed
; water, trunk, hatch open
; prev two, trunk open/closed
; nowater, hatch closed
; nowater, hatch open
; idea: baseline with water trunk, water no trunk, nowater
; draw hatch as sprite
;==================================
; update tunnel lights
;==================================
; only on when BATTERY_CHARGE is non-zero
;
; darkening the rooms happens elsewhere
; here is where we change up backgrounds
; and turn the lighthouse on and off
;
; FIXME:
; + make the top stairwells dark
; + make inside top stairwells display outside still
; + do something about looking backwards from airlocks
