One of the best Sega Genesis games ever made.

A side scrolling adventure game, with over 100 levels, it's almost impossible to complete without using cheat codes. Possibly one of the hardest games of all time.

You play as a kid, trapped inside a video game. You have to make it to the end and destroy the final boss, who has captured you, and won't let you out until you do so. On the way, you'll go through forests, caves, arctic tundras, deserts, and towers in the sky.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
