Nebulus challenges you to climb towering structures within a time limit and destroy them at the top. Its standout feature is the rotating visual effect, where the world appears to spin around the tower while the camera remains centered on your character. As you ascend, enemies, traps and tricky jumps demand careful timing and precision. Getting hit sends you down a level rather than killing you outright, with only a fall into the water ending your attempt. The result is a demanding platform experience built on skill, patience and spatial awareness.
