A forgotten planet.

In Bug Bug in Sky Tower, you have crashed on a forgotten planet, and now it is up to your not-so-automated repair droid to recover the parts to return you on your journey. Search the map for broken parts and equipment you can use and don't worry about death - in BugBug in Sky Tower, you'll always come back to life!
Search the map for parts of your alien craft. The first powerup you find gives you the map, use that to determine where to go and where you haven't been.
Some areas are only accessible once you have a certain item, such as a key. If you can't figure out how to get where you need to go, come back later.
