Roko-Loko no Castelo do Ratozinger

Roko-Loko is a comics character created by Marcio Baraldi, a Brazilian cartoonist for the Rock Brigade magazine.

Roko-Loko must enter Vaticão, castle of the cruel Ratozinger, a religious ultra-conservative rat who hates rock and sex and have prisoned the beautiful Adrina-lina and some famous rock-stars, such as Eddie (Iron Maiden's mascot), Rob Halford (from Judas Priest), Ozzy Osbourne, Gene Simmons (from Kiss), among others. In order to free them, he must face a lot of threats such as spiders, bats, skulls, alligators, volcanic lava and fire balls, and stuff.

Roko-Loko no Castelo do Ratozinger is a three level side-scrolling game. To complete the levels, Roko-Loko must find and take stuck electric guitars from anvils, used to open locked doors. As he advances throughout the levels, he will collect musical notes. Collecting 30 of them will grant him a life. Roko can jump and climb ladders by pressing the up arrow key, and can punch by pressing the space bar.
