Tower Toppler

Castelian is a game where the player controls a character tasked with destroying eight towers to prevent them from contaminating planetary water supplies. The objective is reached by ascending each structure's exterior, navigating walkways and avoiding hostile creatures. Vertical progress primarily depends on timing jumps onto moving platforms.

A notable technical feature for its era was the visual presentation, which created a pseudo three dimensional effect. This was achieved by keeping the protagonist centered on screen while the tower background rotated around them. Between the main tower stages, transportation occurs via a submarine in a side scrolling segment where items can be collected for bonus points.

The core activity involves a combination of evasion and confrontation with enemies during the ascent. The journey to each tower's summit is challenging, requiring precise jumps and dealing with various obstacles along the path.
