Your land has been ravaged by evil forces. Go out and defeat the evil that has come and bring joy back to your kingdom.
Yep, you're a knight in this one. A black knight in an ink-blob world. This is a action-brawler of sorts, where you go about your daily life jumping about slaugtering the enemy before they do likewise to you. Look for power-ups and upgrade your weapons as you go through level by level. Of course, prepare youself for bosses, who will be intent on ripping you to shreds.
It's not easy being an ink-blot, but you've had the training, and you certainly have the spirit. Good luck stopping the evil, and try to make a buck or two along the way ;)
