A remake of the original freeware game released in 2007, Ninjah is now free to download. It's a difficult platformer which combines color switching, a grapple hook, and a gun to deliver challenging levels and a simple but effective art style.
here or if you're feeling generous and wish to support the developer, you can buy it on Desura or XBIG. Chris is also working on Ninjah 2, which will feature a level editor, larger multi-screen levels, and just more levels overall.
