Chris Mingay at Colourfy Games writes in with word that his speed-focused platformer Ninjah is now available as a downloadable Windows title for 99 cents.

Originally released as a freeware game back in 2007 and later upgraded for its Xbox Live Indie Games debut last year, Ninjah is a single-screen platformer in which the object is to get to the exit of each level as quickly as possible. Note, however, that you're only able to touch blocks that are the same color as your Ninjah; you'll need to make skillful use of your jetpack and swing rope in order to survive.

Mingay notes that anyone who buys the Windows version will also receive access to the upcoming Linux and Mac OSX ports of Ninjah, once they're available.
