Put your scavenging and building skills on display in Glap. Explore the galaxy, collect parts, and build your dinky little ship into an absolute behemoth.
WASD controls your thrusters. It's a bit trickier than simply moving, since you have to take your velocity into account. O & P zoom in and out, and just use the mouse to attach parts to your ship. There's also an edit mode to allow you to change your ship safely, and the option to save your progress across game sessions.
Be careful where you try to go when you first start playing. You'll run out of fuel relatively quickly, so explore the closer points of interest first.
