Well :D
Here's my game for LD#16 with theme Exploration. Its name is Planetary Explorer, so you can understand that it's about space travels and exploring. You're right!

It's made with Game Maker 6.1 Pro and converted to make it compatible with Vista and Win7. Sadly it's not compatible with Linux or Mac, even under Wine. Other tools used:
Graphics: MS Paint and Gimp
Music: Anvil Studio

It only has one level, with two parts:
I: Travelling to the planet with your ship, destroying enemies and avoiding bullets.
II: Once in the planet, finding three diamonds and returning to the ship.

I also made some songs for the game.

Hope you enjoy playing it as much as I enjoyed making it.
See you in next LD!
