The planned game uses a side-view platforming format. Bignose moves through prehistoric stages, avoids hazards, and confronts enemies while advancing toward the end of each area.

The surviving documentation does not reliably establish the complete stage structure, modes, scoring system, or progression mechanics. Confirmed platform-specific controls and a final game layout are therefore left unspecified.

Use a cautious approach: inspect hazards before moving forward and avoid assuming that mechanics from other Bignose games apply here. Since the Master System project is not documented as a complete retail game, level-specific routes and reliable boss tactics are unavailable.
