This game is by a little known game developer called webfoot. It is a truly unique game and can only be compared to lemmings. Just like lemmings you are trying to save something (h2o in this case) by creating a path from the entrance to the exit. Unlike lemmings you don't actually do anything to the h2o itself but rather put up blocks and tunnels to stop the flow. The graphics are rather good although the sound and music really don’t fit. It is an addictive game that will challenge most players for hours.
