Venture the Void is a huge, detailed game, but the basics are actually pretty simple:

1. Pilot your ship in smooth 3D from planet to planet, shoot aliens, hail friendlies, grab cargo, and explore strange new worlds.

2. Park your ship at any city or other site, and get a birds-eye view of it. Click a building and head inside.

3. Plunder the locals(...or help them out...) and do a thousand other things in a deep, engaging, and just plain funny text adventure.

Of course, this is only meant to get you started. When you need some more help, check the Manual or post to the Forums.
