After you get rid of one bunch, an evolved bunch of aliens will appear.
The aliens evolve based on how well they hit you and how long they stay alive. You can prevent the aliens from taking too much advantage of it by killing the nastiest ones first and dodging their bullets.
Windows: Completely self-contained zip; no installer; just extract and run. Linux: Executable python file. Requires pygame.
Apparently the Windows version fails to work on some computers - if it doesn't work for you, leaveing a note here with some general system info would be of great help.
Hell, for some reason half of my description and all the links keep disappearing from this site... does anyone know what is going on? I'm re-adding them again...
Krise20: It does not require python; it is a cx_Freeze build - it is referring to the original file names of data it copied to the package from the original system. Anyway, win7 x64 - that is useful info.
madpew: It is not a trivial fix; the error happens in a built-in file of python or pygame - I can't do anything about it other than use a different python-to-exe utility. I'll try py2exe instead of cx_Freeze once I get home.
I can't play it :/ I get this error: "UnicodeDecodeError: 'utf8' codec can't decode byte 0x90 in position 2: invalide start byte. I run windows 7 32bit

Nice retro remix :D. Extra star for the timelapse!
I played it several times in different ways. I saw evolution, and different alien types and behaviours, but I'm not sure that I saw much adaptation to my game play. How did you judge fitness?
badlydrawnrod: You may have stumbled upon the small amount of genes and variable properties - the aliens only have a couple of major killer combinations to evolve into.
Basically the genes of the aliens that managed to hit the player are mixed with the genes of aliens that were not immediately killed, plus some mutation. Of a new bunch, 2/3 of aliens are those inherited ones, and 1/3 in a bunch are randomly generated. The first bunch contains easy aliens in place of the ones that would be inherited.
A bit ago I managed to get 16660 points by continuously avoiding all hits and always killing the nastiest aliens first - it will give you very easy time for long - until you get hit by a very nasty random one - then the hell begins and you are basically doomed. Theoretically you could play infinitely with aliens like the ones in the first group.
Awesome, game! It's really addictive! I like how you managed to blend *actual* evolution with an arcade game! Great job! 5*'s for Innovation, Fun and theme.
It just needs a little tweaking. When choosing the next generation, I suggest putting more weight on the survival time and less weight on how well they damage the player. As it is, the player isn't able to affect the breeding that much, and the aliens quickly converge on tearing the player to pieces.

For me, you cannot do anything wrong with a space-invaders clone. liked it.
