Ninja Senki is the brain child of Jonathan Lavigne and is a throwback to old school platformers with refreshing gameplay. The download for Ninja Senki comes in under 10mb so it is worth a try and will not hog up your hard drive space. Here is what the creator has to say about his creation:
You play the game as Hayate, the shurikenjutsu master, who embarks on a quest to avenge the death of Kinuhime, the princess of his clan.
I played a few levels and it definitely is frustratingly fun, skillfully involved game that I thought it would be. Did I mention that it is free to play on the PC and works with a gamepad. So what are you waiting for go get it at NinjaSenki.com.
