Gameplay: A Lesson in Primal Survival The premise of the Dinosaur Game is elegantly simple. You, as the aforementioned T-Rex, must perpetually run across a desolate desert landscape. The only obstacle between you and survival? Cacti of varying sizes and the occasional Pterodactyl soaring overhead. https://dinosaurgamerun.com The controls are equally minimalist. Pressing the spacebar (or the up arrow key) makes the dino jump. Pressing the down arrow key makes him duck under the Pterodactyls. That's it. That’s the entire game.
