caged by force fields, the player can warp out to continue playing. Boulders hang below each platform. When the player rolls away from a boulder, they will either discover nothing, some dino eggs, or some bonus feature like a power flower or hidden log. Snakes, spiders, and centipedes hit by the boulder will be smashed to death, and fires will be reduced to energy level 1. Eggs which remain covered by a boulder are neither visible to the player nor subject to hatching. Baby Dinos face far more hazards than do the nearly invulnerable eggs. First of all, the player's touch will destroy them. Secondly, they must avoid the safety fire, as they may accidentally wander into it and be burned to death. Thirdly, on higher levels, spiders may attempt to abduct them. The death of a Baby Dino by any means results in a deduction of ten points from the player's score. Caged baby dinos will not wander into the fire and are protected from being touched or abducted, but are not immune from falling boulders. The game consists of four levels of platforms. Via stone ladders, players can climb up to and jump down between gaps in the four platforms (the player can climb down the ladders, but by using the "jump" button, the player will fall down the length of any ladder he is presently climbing; this trick enables the player to descend to the lower platform more rapidly). The bottom platform is continuous with no gaps. The screen is wrap-around: Exiting on one side, the player will enter on the other side of the screen. After collecting one or more eggs and/or detaining one or more Baby Dinos in force fields, the player may "warp out" by delivering the Baby Dinos back to the future. The player will then return to a different location on the same level, and attempt to save more eggs and Baby Dino hatchlings. The player may leave a level permanently at any time, by warping out while not carrying any eggs, with no Baby Dinos detained. By leaving the level, the player will receive a bonus for rescuing all hatchlings and all eggs and then move on to the next level. However, if the player warps out without collecting all of the Baby Dinos and/or eggs, points will be lost for each Baby Dino egg and live Baby Dino not collected,
