The game uses a side-scrolling perspective with straightforward movement, jumping, and punching or kicking through enemy waves. Defeated glowing enemies drop spirit orbs; collecting enough triggers a transformation into a stronger beast form. Each stage grants a different beast with its own attack patterns, movement feel, and special abilities. Progress is linear, with stage-end bosses that demand pattern recognition, spacing, and careful use of the transformed state.

Prioritize glowing enemies to build spirit orbs quickly, because transforming is the safest way to push stages. Stay disciplined before transformation and avoid getting surrounded. Once transformed, learn the range and timing of each beast's attacks and use the form's strength to clear crowds efficiently. Against bosses, play patiently, watch attack patterns, and punish openings instead of trading hits.
