ZuPaPa! is a 2D platformer, completed in 1994, but released after years in 2001.
The game is very similar to Nightmare In The Dark. The player character Zupapa is a blue, cute creature, walking and jumping in small levels and eliminating the enemies there. He can use "Zupipis" - little creatures that can immobilize opponents. Four Zupipis are available - green, blue, orange and purple. After defeating all the enemies, the player goes to the next level.
ZuPaPa! has nine stages, six selectable from the start. At the end of each stage, a boss fight awaits.
