The game uses a side-view perspective. Players guide Fred or Barney through linear stages filled with platforms, enemies, hazards, collectibles, and occasional vertical sections. The main objective is to reach the end of each area while surviving attacks and collecting useful items.

Fred and Barney have different movement and attack characteristics, so choosing the better character for a particular obstacle is important. Stages are played in sequence, with boss encounters and themed prehistoric locations providing progression. The game is primarily a single-player experience.

Learn the timing of each character's jump and attack before rushing through a stage. Use the character best suited to the current obstacle, and avoid unnecessary contact with enemies because recovery opportunities can be limited.

Explore platforms carefully for collectibles and useful items, but do not let optional detours cause avoidable damage. Against bosses, prioritize safe positioning and attack only after their movement pattern is clear.
