Keepers of The Harmony

by chunkyguy - 48 Hour Compo Entry

I've ported the game as Java Applet using Processing. It's not as good as original for 2 reasons, one I don't know java much, two it's not fun porting code and three I'm still fixing it.

I've tested with Firefox.

If the game crashes on your computer, install SFML.
Get it here:

The game is about a parallel universe where there are 5 species living in harmony, that we call as:
Huge, Big, Medium, Small and Tiny.

Each organism (of any species) has a certain lifespan, and at the end of it's life if reproduces certain number of children.

Now, as in every other world the resources are limited so no species is allowed to have more than 10 organisms.

And neither can there be 0 organisms for any species.

You are their God, and it's your duty to keep the harmony intact by eliminating extra organisms of any species or avoiding any species to extinct (don't kill the last member of any species)

Any keystroke to enter game or shoot from your 'Darwin Gun'.

"Check with the developer to make sure Evolution works with this version of OS X."

I'm running Mountain Lion.

I'm sorry for that, I tested on two Macs both running Mountain Lion. I guess the problem was with SFML libraries not linked. I've updated the build please try it now, it should work. If it doesn't you can also inform me directly at twitter:

I'm taking a look at the crash, in the meantime you can install SFML on your system.

It's been ages since I made a Mac app, but can't you bundle the library inside the app?

I tried embedding private frameworks and it's running perfectly on my test machines, but people are still reporting about the crash. And this is my first time ever making an App for Mac OS X, maybe from next time onwards I'll be more smarter :)

I hope a Windows or Web Build is coming soon.

Seems to be working for me now! I'm on mountain lion, the first time it opened it said I needed X11, and so I clicked a button and installed it, and now it runs!

Cool idea for a game! The thing that I don't really like is the interaction that I (the player) have with the game world is so limited with only one action, it would be cool to have more ways to affect(effect?) the population of the different organisms. Well Done though! glad i could get it running

That's a huge relief. I'm trying to redo it with Processing. I've no idea why it asked for X11. Maybe SFML is using it. Lesson learned from this year's event, write your own OpenGL engine using.

Actually the reason why kept only action is because I'll probably do this game for mobile devices, where less interaction is good

The barrier to installing and getting this game running was too much for me. Stuff really needs to run out of the box for a comp like this.

I ran the web version properly. I liked the concept, although too much text at the beginning. I liked the idea of keeping the species equilibrated. Thanks!

Very simple. Too bad that species are just squares not some sprites.
