Ever heard of Chip's Challenge ? If you have or had an Atari Lynx, you probably did. If you never had a Lynx buy on and buy a Chips Challenge cartridge and Ill hear you again after a week or three.....

For me it was the best game ever on the platform, not to say one of may favorite games on any platform.
The funny thing is that I'm normally not very keen on puzzling games, but then again, this isnt really a puzzling game. It has elements of puzzling, but just as well arcade like game play. You just have to try it to understand. It also has a very well balanced learning curve.
There is also an official 16 bit Windows version but it doesnt play as smooth and silky as the Lynx and has some differences, not to mention bugs...
Later, using Tile World I was able to play it (Lynx style) on PC and Mac, but I just discovered that Chuck Sommerville, the creator of the game has published an "official" sequel for the IOS platform called Chuck's Challenge !!
Check it out right here and if you have an iPhone or iPad download it from the app store. The first 25 levels are free.
