Red Ball 4 Volume 2 continues the story into new environments, with the same rolling physics and a harder set of puzzles: more moving platforms, more machinery, and boss encounters that need pattern reading rather than reflexes.
The physics remain the heart of it. The ball carries momentum, so half the difficulty is judging when to stop rather than when to go.
No — each volume works on its own, though they continue the same story and get progressively harder.
By pattern rather than reflex — watch a full cycle of the boss's movement before committing to an attack.
Yes — a light 2D game with nothing to install.
