After some tinkering around yesterday, I have decided to proceed with the ninja game, even though I should be working on other things (capricious, I am).
And it shall be named Yami no Mono (People of Darkness).
...and like the obsessive nutcase that I am, I already made a logo and cover for it, utilizing my favorite ninja-portraying actor, Sonny Chiba.
More on this later. Gotta get back to work (that is, work I am actually paid for).
