Well, I ran out of time. =) This is not even the gameplay that I intended and it is not playable (unless you like to lose). I spent too much bloody time on collisions and missile trajectories, etc.. The “daleks” that you see in the screenshot were going to be gun turrets which you use to shoot down incoming missiles. If enough missiles hit the ground, the ground is destroyed and your tower plummets. I had other buildings and a point to the whole thing, but those were plans that had to be thrown out. I think with another hour to two hours, this could actually be playable, though not polished. My greatest regret is that I did not get a chance to rotate the missiles so that they point in their direction of travel.
Here is the zip. Download and run at your own boredom.
python source (64K) Needs pygame and pyopengl.
Edit: Uploaded new version with a .bat file that uses CRLF terminators.
Edit 2: Uploaded a non-zero length archive (for ‘archival’ purposes now that judging and whatnot is over). Not really sure how that happened in the first place.
