The storyline is about a little alien boy named "Cosmo". Cosmo's parents are taking him to Disneyland for his birthday. A comet hits their ship, forcing them to land on an unknown planet and repair the ship. Cosmo goes exploring, and when he returns, his parents are missing. Seeing large footprints, Cosmo thinks that his parents have been captured and sets off to rescue them before they are eaten. There are 3 episodes in the game series in which Cosmo must navigate through 10 alien-themed levels. At the end of the first episode, Cosmo unexpectedly gets swallowed by a large creature. The story continues in the second episode, where Cosmo ends up in the creature's body and has to find a way out. At the end of the second episode, Cosmo finds the city where he thinks his parents might have been taken. In the final episode, Cosmo finds his parents (who were in no danger of being eaten the whole time) and has a great time at Disneyland for his birthday. Cosmo's Cosmic Adventure is a video game programmed by Todd Replogle and published by Apogee Software in 1992. It is a two-dimensional side-scrolling platform game produced for the PC platform, and features 16-color EGA graphics at 320×200 screen resolution. Working titles for the game include The Adventures of Zonk and Cosmo: Kid From Space. The game's technology at the time was comparable and in direct competition with that of Nintendo's Super Mario Brothers 3 for the NES (which was released several years prior, but was still selling well at the time). Although Cosmo contained superior graphics capabilities in the form of three-layer masked horizontal parallax scrolling, this feature came at the cost of the game's frame rate, moving the graphics in increments of 8 pixels (the size of one game tile) instead of 1 pixel. A file contained with the shareware version of the game urged people not to download it if their computers could not handle it. While the game supports AdLib music, it does not support SoundBlaster sound. The sound effects are instead generated by the PC speaker. The title screen music is based on ZZ Top's "Tush".
