Tidalis is a block-based puzzle game with casual appeal, hardcore depth, and an addictive new "streams" mechanic. The basic rules of the game are this: blocks fall down into the board and have a color and an arrow direction. If a stack of blocks exceeds the height of the board, you lose. In order to clear blocks, you must right-click and drag paths through the arrows to set up chain reactions of like-colored blocks.
Tidalis is the second standalone game from indie developer Arcen Games, known originally for their hardcore RTS/4X hybrid, AI War: Fleet Command. Not wishing to be typecast, and having game and level design backgrounds in a wide variety of genres, Arcen chose pretty much the exact opposite genre for their second game. The final game will be complete with Arcen staples such as co-op, huge amounts of content, and attention to depth and detail -- Tidalis is extremely easy for casual players to pick up, but it will also keep hardcore puzzle fans entertained for months. Coming to both Windows and Mac OSX!
