Requires XNA redistributables - see my site at http://sites.google.com/site/haitaka/ludumdare16/ for details. Will only run well if you have a super overpowered machine, because I didn't test large-scale fights until it was too late ><

Build a fleet, explore the star cluster, and find the aliens - before they find you. The whole game can be controlled using the mouse. Spacebar pauses the game - you can issue orders while paused (theoretically).

To colonize new planets, you need to move a colony ship to the little circle above the planet, then click the "Colonize" button (which only appears when the colony ship is the only thing you have selected).

This is pretty incomplete, but I ran out of time.

Thanks. I'll remember to upload the source code before judging is over. The source code for my pre-prepared library is already on my compo webpage.
As for the models, they were done in Milkshape - took about 5 hours. I wasted a lot of time (1 hour) on UVW mapping because my texture map was laid out in a stupid way, but after that I just kept cloning the same blocks and re-arranging them into a unique silhouette for each subsequent ship so I didn't have to do any more mapping.
The game actually contains models for 4 more alien ships, and textures for 2 space monsters (Space Crystal and Space Mushroom), which I didn't have time to implement.

Sorry, I'm not sure why it doesn't work for you. Utena's entry uses XNA with VS2.0 and PS2.0, same as mine (AFAICR), so if that one works then this one should too. :(
