I'm really digging this game- probably the crown jewel of indie gaming. The music and art/animation is great in this platforming puzzler, but as it progresses it's clear that a controller is a better input device than keyboard. Hook up an Xbox 360 controller and go to town. I can't recommend it highly enough- it's up there with Portal in innovation/execution.

It's another platformer, and probably best if you have nostalgic recollection of the original on NES. This is a remake, and a very good job. I'm enjoying it a lot. Just don't pay more than $10.

This one's almost a hardcore platformer, except that near as I can tell you get unlimited lives which is good 'cause you'll need 'em. Great music, a fun job with retro graphics, and I think it's cheap (got mine in a pack). I'm really digging this game, and if you're looking for something different...
