Castelian is a puzzle platformer in which the basic goal is to ascend towers from the base to the apex. Poro, your frog-like character, is tasked with demolishing these towers by planting a bomb at each tower's top after finding the right route up the tower.
The game was also released on other systems as Nebulus, Kyoro-chan Land, Subline, and Tower Toppler. Nebulus is the original name of the game when it was first developed for the Commodore 64 and ZX Spectrum. Kyoro-chan Land is a licensed reskin starring Kyoro-chan, a mascot for a Japanese chocolate brand named ChocoBall, with Kyoro-chan replacing Poro and ChocoBalls replacing jewels.
