The game uses a side-scrolling perspective. Buster moves through themed nightmare stages, defeats enemies, avoids hazards, collects items, and reaches an end-of-level confrontation or goal.

Stages are arranged as separate areas with platforming routes and combat encounters. Progress comes from clearing levels and advancing through the dream scenario; the emphasis is on timing jumps, managing enemy attacks, and learning each stage's hazards rather than on open-world exploration.

Learn the timing of Buster's jump and attack before rushing through a stage. Clear nearby enemies first when they can interrupt a jump or push Buster into a hazard.

Explore platforms carefully for useful items, but avoid taking unnecessary damage while searching. Against bosses, watch the attack pattern, strike during the recovery window, and keep enough room to retreat.
