Lightspeed Alpha by Xella

Lightspeed Alpha is a game inspired by Faster Than Light, where you control a spaceship traveling around and fight against progressively stronger enemies!

This game has never been fully finished but does work and is in a state where you can buy fuel, upgrade your ship and fight up to 14 different types of enemy ships with over 3 different tiers. The further away you are from the origin, the higher the tiers of the enemies you encounter!
