You're so bored in science class that you decide to do some doodles where you're being attacked by zombies, science teachers, fish-- all sorts of crazy things. Defend yourself with your ink gun by shooting their heads until they blow up like a balloon. When you earn enough experience, you can use it to buy better weapons.
It may look like just some innocent doodles, but don't be fooled, this game is harder than it looks. You'll need to be quick to keep your stickman from getting eaten. Some of the monsters even throw ink back at you.
Whatever you're being attacked by, remember to aim for the head. Good aim, platform-jumping skills and the right weapon will help you survive... at least until the bell rings. Soak 'em with ink 'till their heads pop!
