B.C. II: Grog's Revenge

B.C. II alternates between cave-crawling collection runs and obstacle-dodging races across prehistoric terrain. You're Thor, gathering clams in dark caverns by sweeping a headlight beam across jagged stalagmites—100 clams buy passage through the next mountain gate. Above ground, you race against Grog, who steals your clams while you dodge potholes, rocks, and pterodactyls trying to steal your wheel. Lose that wheel and you're stuck. The loop: spelunk for currency, spend it on access, outrun Grog, repeat. It's a 1984 platformer-racer hybrid where resource management matters as much as reflexes. Tight timing and pattern memorization separate progress from restarts.
