This was one of my favorite games as a kid on C64. The running on the dino vault you pushed left and right in a rhythm faster and faster to run I remember. The fire stater was the same back and forth rhythmically then up and down to blow. They made it work pretty well, at least my memory of it. 😅
In the Pole Vault, you can press up in the pre-game to raise the dinosaur's head height/neck length. It's kinda funny. In Fire Starting, you can bonk the other player over the head with your stick - if they don't duck their head. In Clubbing, if you press a button combo (I used to just mash as a kid) when the meteor's going by in the background, you do some weird super-move and blow the opponent off the edge all at once.

My brother, my cousins who lived next door, and myself used to play this all the time as kids. I was terrible at it, we never played against computers though so I have no idea how hard they are to compete against.
