Tower Toppler on the Commodore 64 (better known elsewhere as Nebulus) is a clever action-platformer where you guide a little creature up a series of massive cylindrical towers, dodging enemies and tricky gaps while racing the clock. The standout hook is the rotating “wraparound” viewpoint that makes the tower feel truly 3D as you move around it, turning simple jumps into brain-bending spatial puzzles. It’s tight, upbeat, and surprisingly tense—one of those classic C64 games that feels both arcade-fast and ingeniously technical.
