Right now the game can't launch, it fails to find the "worldmap" module at l797!

Thanks; I've updated the tarball to include worldmap.py and DejaVuSans.

Writing what compiler it should be compiled in might help. (Python)

Just the source?
Good luck getting people to play it.

Well I did play it. Every programmer should have python installed anyway and pygame is just another lib. There's no need for compiling anyway. :3

But while I believe there's no harm done here, you could try and package this into a nice exe (unless you're on linux-only environment, but then - some virtual machine would do), or at the very least, write what are the keys to use in your game. I had to dig in your source to check what I can do. Some hints:
p: load slot
s: save slot
b: doesn't work :P
m: mutate current organism
1-9: select mutated organism
space: start playing (arrows: movement, pgup/pgdown: dive up/down, +/-: zoom in/out)

I like where this was going, although it's definitely not finished. But it's not unplayable. You did implement a lot of features - shame you didn't manage to finish, but the idea was pretty cool. Mutation stuff seems to work quite well, as well as moving/swimming in the world. This might have been a little too much for LD, but I believe you were onto something really interesting. Maybe try to finish it as a post-compo? I would gladly try this one out again.

Please make an executable next time. Not everyone has Python, or knows how to execute py scripts.

^^^What Desi said.

I'm sorry. Just installed Python, think I installed pygame corectly, but the games's not running. Maybe I'll try again after the compo, but with just a few hours 'till the deadline, I'll pass.
