Out of all the point and click classics DotT is, to my mind, the best of the bunch, hands down. The puzles are hard enough to cause you to think, but not as ludicrus as some of it's contemporaries. The updated graphics work really well and keep the art style in tact. I can run through the game in about 2 hours, but if you try and solve it without help from online it's gunna take you quite some time.
