40d:Water

Adventure mode: Water preference (when possible or when necessary) is set by pressing the m key, and moving onto a water tile can be done using the 'careful move', or alt+direction. Alt+direction (even numpad+5) seems to be working for up and down. (Need confirmation on the up and down, I was told by a beta tester that "Swimming up is Shift + 5(numpad), and swimming down is Ctrl + 5(numpad)". , but does not seem to be working)

Dark-colored water, when looked at, shows up as an 'open space'. This is because it is actually located one level below the camera level. Moving the camera down one level will cause the water to turn light and show up as actual water. Note that to specify a pool of water as a water source, fishing zone, or pond, you need to create the zone at the level above the water. The "level above the water" is the level at which the surface of the water is at foot-level instead of ceiling level.

Water in adventure mode seems to be very 'unwelcoming', and if you enjoy your adventurer, avoidance is highly recommended. If an untrained swimmer enters the water, three things happen, they start drowning (which happens to any level swimmer, I believe, since this kind of represents their breath), they are stunned from the impact and subsequently are forced into a prone position (panicking/thrashing?) and are forced to little under a third of their speed, probably raised by raising the swimming skill level.

Also, there seems to be several water-types on the world map, as well as on the adventure map. The world map seems to be influenced (red tiles) as well as content of the water-- muddy water gets brown tiles. On the adventure map, there are also types of water: stagnant, murky, salt, mud(dy?) and ice. -- Twerty (Will add more/confirm A.S.A.P.)

If you dig through to an area of cavern with 777777 depth water, it is NOT a pond, it is a chamber full of water that will make your wet as they continue to dig through level 2223334444 etc. water while it releases itself.

If you dig into a small pond, it will spill out of the hole. If there are fish in it, they can be found flopping out of the water once it has spilled!
