This game was exported in Flash and, as you probably know, Flash has been discontinued. As such, I can only provide access to the source code and the .swf file at the moment.
If you happen to have an ancient computer that still runs Flash in the browser, or a copy of the Adobe Flash Standalone Player, you should be able to run the game.
At some point I may port the game to JavaScript or similar, and it’s possible that the ruffle Flash emulator will get to a point where this game will run again. Let’s see.
War Game was written in ActionScript 3 using Adobe’s FlashBuilder 4.6 and the excellent Flixel library. Sound effects were made in bfxr. The screen font is Digital 7 by Chess 7 and the label font is Misery Loves Company by KC Fonts. Much inspiration drawn from Pica Pic, especially Sub Attack.
You can read my writing about the game on my blog. War Game was featured on Kill Screen, Game Church, The Verge, and IndieGames.com.
