N (Metanet Software)
One of the most addictive and sometimes frustrating game you can ever play, N is an award winning title that involves tons of jumping, climbing, running and all those other cool ninja skills.
The game was created by Metanet Software back in 2005 and won the audience choice award for the Independent Games Festival that same year. Today, the game has spawned a console (multiplayer) version for the Xbox Live Arcade, the Nintendo DS and the PSP titled, N+.
N was originally offered as a flash game but you can download it now onto your computer. There's a version available for the Mac, Linux and of course, Windows system.
