What the game feels like
The objective is straightforward: steer the ball through mazes full of traps and moving hazards. Levels are cluttered with obstacles that demand timing and quick reactions, making each playthrough fast-paced and tense. The mechanics are intentionally simple, so newcomers can pick it up immediately while higher speeds and trickier layouts keep experienced players challenged.
Controls and input

These two inputs form the core of the experience, relying on timing rather than complex button combos.
