Interesting game! I included it in my Open Jam 2018 compilation video series, if you’d like to take a look. :)

The graphics are amazing and the concept is quite interesting !

Jam Host

Congratulations you earned 5 Open Source Karma stars!


Interesting concept. Really impressing graphics for this short jam.


Really liked the game! Music and graphics fit nicely contrasting with the serious matter that's nuclear war. Once you get the game it gets too easy, but that's fine.

I'm also glad to see more Godot games!

Thanks and keep the good work!


Thanks! That's great to hear - the style and music was very intentional, so it's especially good to hear feedback on it.  And also, we were worried about the difficulty balance, with so little time to test it - I think we were worried it was too hard (there's an OK ending and a better ending). 


Oh, noes! Two endings? Now I need to get back and get both!


The special victory is slightly bugged in this  release unfortunately. I know how to fix it but I'll have to wait until after the vote to be fair. We wanted it to be a kind of secret ending players could discover if they wanted more of a challenge - if you survive and destroy all your enemies before the World Population reaches Critical (under 1 billion), the special blue Triumphant message should appear (with fresh pie). However, I must have mucked it up fixing another bug in the minutes before release and we didn't notice it in time. So it goes. For now, I guess you'll have to use your imagination. I am glad to hear you enjoyed it!


The good part of FOSS is that I can check the original source code, open it on Godot, and have a look at it.

Anyway, thanks for the game!


I didnt get the ga,e at first, all those pretty colours and the flishing triangles made me dishorientated, but after a while i kind of got the hang of it. I just wished there was some more to this game. Great work overall!


We wish there was more to it too! But four days is only so long and real life does exist so we had to cut quite a few of our initial ideas to get it out the door in time. FYI, there's a How-To-Play window accessible from the title screen, hit ESC to make it show. If I update it post-jam, I think it would be better if it were also accessible from the main game and a bit clearer, but I didn't think of that in time. I already knew how to play. :) If you've got specific ideas for what you think might be a good "more to the game," I'd love to hear what that might be.


Oh...i didnt realized it until now, yes, indeed there is a how to play screen in the title screen, my bad. Tho it doesnt say all the sceneraios, i had several different winning messages, and i didnt know what they ment until i keept getting them. Also sometimes i won without doing anything, perhaps a glitch of some sort?

You can maybe expand this game a bit more if you find something interesting to implement, i would love to see it. I cant think of something, but perhaps your brilliant minds can come up with something.


Amazingly done, pressing the button really feel like doing something meaningful here rather than a chore. My only nitpicking suggestion is to allow starting the game with keyboard as well, which is as fast as setting the default selection to start and allowing options switching with navigational keys. Otherwise, the level of polishing is over the top, I really want to give more feedback but I don't know what more to add to this game. Very well done!


Do you mean starting from the title screen? You should be able to just press "Enter." You're right though - it doesn't say that outright anywhere. A little key icon would be a great addition for a post-jam update. Thanks for the tip! Glad to hear you enjoyed it. :)


I see, maybe an outline to show it is currently selected would be awesome. Still, supporting both keyboard and mouse input for button is such a well-thoughout design!


I really like this game. I'll try to give a bit more feedback tomorrow but I just wanted to encourage you to add a web version. I think you will get much more plays if the threshold to play is as low as possible. Exporting to web with Godot should not take too much time and I think the organizers are okay with uploading the same version of a game just for a different plattform.


Thanks for your feedback, syntonym! I had tried once already, but I decided to go back and figure out how to get a HTML5 version working because of your comment. I'm sure you're right that that is why nobody was playing it. :) Hopefully that changes now.


Nice that so many users played the game in the end! This is my personal favorite of the jam. Graphics and mood are stellar. The only real room for improvement I see is adding features to the gameplay. After winning 1~2 times I feel like there is no more place to improve my playstyle.

One thing I could imagine is some kind of defensive maneuver. When playing I never looked at my own city as I couldn't do anything about it anyway. When there would exist e.g. a shield that you could activate you could lookout for incoming missiles to detect against them.

This is not meant as critic but just as a pointer what could be added if you wanted to. For the short time it's an excellent game.
