"Hey, I wonder if there's any fun 2D bossfight game with a cartoonish design." 

Well, there it is! This amazing game has 10 bosses with unique mechanics, a boss creator that lets you turn any image from your computer into a bossfight (don't make me regret it) and a really funny design! By the way, it was made by a single person, because I know you wouldn't play it if it was made by some random big company. Hope you like it :)
