Dino Eggs is an Apple II platform game designed by David H. Schroeder and published by Micro Fun in 1983. It was ported to the Commodore 64 by Leonard Bertoni and the IBM PC as a self-booting disk. Dino Eggs is Schroeder's second published game, after Crisis Mountain. Description The player's objective as "Time Master Tim" (a time traveler) is to collect dinosaur eggs and rescue hatchling dinosaurs while avoiding snakes ("proto-snakes"), gigantic spiders ("proto-spiders"), flying creatures ("proto-pedes"), and the dinosaurs' mother (or "Dino Mom"). Physical contact with any creature will cause the player to be contaminated, and the player will experience "devolution" into a prehistoric spider and lose a life unless the player returns to the "time warp" transport force field before a de-evolution timer runs out. Contamination also destroys eggs and hatchling dinosaurs on contact, reducing the player's score. While within the transport force field, Time Master Tim is safe from all creatures except the Dino Mom. Hazards A player's first hazard is the Dino Mom. The mother dinosaur will try to crush the player by stomping on him. When starting a level, a player has a short period of time to build a fire to keep her away. Building a fire is done by collecting one of several logs present in each level and placing that log on top of another. The player then tries to collect all the eggs and hatched baby dinosaurs before the fire goes out. A fire started at any time will prevent the Dino Mom from stomping. Even if her foot is coming down when a fire begins, she will pull it back up. The player can also attempt to rescue the eggs and baby dinosaurs without fire by avoiding the mother's enormous stomping feet. On each level, the player is presented with a number of dino eggs, some of which eventually hatch into baby dinosaurs, and all of which must be rescued (in the event they are not killed or destroyed through contamination beforehand) to complete the level. The player does this either by collecting the eggs before they hatch or by placing a time-transporting force field around each baby dinosaur by jumping over them. Other hazards include snakes, spiders, and centipedes. Snakes appear out of thin air and disappear again after a period of time, and can be avoided by jumping over them. In higher levels, centipedes appear and run
