I was recently reminded of an old 1990 Nintendo game I used to own, called "Trog." I mention it because it was dinosaur-themed.

It was a one- or two-player Pac-Man style game where each player had to collect all of the eggs of their colour, while avoiding various hazards on the level, including cavemen who tried to eat you, tarpits, water, and really deep holes.
The attached file includes a few screenshots of the game. Anyone else remember this awesome game?

I didn't play far enough in to take screenshots of the later levels, which get very interesting (cavemen that can jump, maps with different shapes, doors, other fun stuff). There are (I think) 50 levels and (I think again

) 3 bonus games in total.
