Yup I think it's because of outlines if you think you failed! But try again and again, until you find your style!
The brief of the game :
You're an inkman, and you have to make some tatoo for random people, then for each people there's a level, you need to found all the items who compose the tatoo, the three jar of ink on the right top of the screen is your 'life bar". And well, villains and traps of course!
Just a platform game.
