I just played Tilelander game demo, which is a nice puzzle game, although it can be played in two modes: puzzle or action. I liked the action style more.
Tilelander’s opponents react to player actions in a “respectful” manner, only moving if the player does so: The player can thus set the pace, playing with careful thinking behind each move or in a furious spree. Tilelander includes over 70 puzzling levels combining a variety of gameplay, from peaceful tile filling and Gauntlet-style maze solving to involved shoot’em’up and end-of-level boss fighting.
Game screenshots and a demo version can be downloaded for free at Ludimate.com. Basically, if you are looking a fun little game, check out Tilelander.
