Flintstones The Surprise at Dinosaur Peak

In this game you can control one of two characters at any given time, each character also has their own unique qualities.

Fred - Can swing his club harder by holding B and releasing according to the POW(er) meter. He can also grab onto ledges while you hold A, and climb up onto them when you press up.

Barney - Has a long distance sling-shot for a weapon, he can also climb onto narrow poles since he's lighter than Fred.

Use Fred for now as you walk right and kill a lizard, then club the red barrel for a heart. the bird on the roof ahead dives diagonally at you, so club him when he gets close.

Hang off the edge of the roof (hold A) and press up to climb onto it, then do the same to get onto the ledge to your right. Club another lizard and bird to your right, then switch to Barney and hang off the pole above.
