This is a slightly more polished version of my Ludum Dare 23 entry The Spaceman (play the original here: http://www.ludumdare.com/
Arrow Keys - Move
X and C - Shields
The Spaceman is a top-down exploration game. You play as an astronaut who's crash-landed on a strange planet.
The main thing I decided to experiment with this project is a game where you lose abilities over the course of the game. At the beginning of the game, you have two crystals which allow you to shield yourselves against the two colors of enemy projectiles. However, in order to progress, you need to deposit the crystals in pedestals, leaving you without their power. I also wanted to make the game very non-linear, letting you find your own path through the world.
