Mixing a puzzle-platform game with the 3D's isometric graphics of the 8-bits NES (Nintendo Entertainment System), Castelian sets in Centrus, a double-sun planet with summer as only season and the island of Jemmerville as deposit of a precious gems that it's the envy throughout the Triangulum galaxy, and too the envy of almost every life-form in this corner of the universe. But this tranquility ends when eight alien towers enclose Jemmerville, cutting off naviports and trapping hyperfreighters in order to steal all the gems. President of Domoloco and Sons Inc., owner of the gems, summons Julius to topple and conquer the eight towers to save Jemmerville. Use D-bombs, learn to know which doors of each tower are false and which are true to cross the tower inside it, take care of the bouncing I-Balls that looks like an eye, avoid any touch with the Tri-Zeroop that are like three spheres together, defeat Metaflii that it looks like a six-legged spider and collect all gems as you can in the intermediate levels after each tower, but look out: if the invincible Hexalon touches you (an egg with four spheres that it crosses the screen each little time from a side to another), you will fall to the platforms below you, and time doesn't awaits for anybody.
