DecapAttack

DecapAttack is a platformer starring Chuck D. Head who is sent on a mission to stop the demon Max D. Cap (...) from conquering the surface world and to put the pieces of the island back together. This game is a retooled version of another game called Magical Hat no Buttobi Tābo! Daibōken which was a licensed game based on an old anime from the time. That game in turn, is essentially just an updated version or semi-sequel of Psycho Fox which in of itself was preceded in the same vein by Kid Kool... The game itself is alright.
