Hi, can I ask you how you make your game go to fullscreen on another page?

Why does it take so long for things later on with nothing to speed it up? Also, the blocks keep on disappearing after a certain point, and its really really annoying how much that happens.(I do not know how to blocks work)

Really cool game, heavily reminds me of Universal Paperclips

Am I missing something here? I have no idea what to do or what is happening from a gameplay perspective. Am I supposed to make patterns with the light blue blocks? Am I earning currency? Since nobody else seems to have questions like these, I'll just conclude that I'm a dumbass, but it might be worth explaining what's going on for the benefit of less tech-savvy players

Edit: it took me way too long to realize arranging the blocks at the top of the visualizer was speeding up operations. A hint alluding to this could be given with the other instructions in the cmd prompt.

Thanks for the feedback! You're not alone -- the need to place cells in a row and no other pattern has been reported by other players as well. I added a tip to the gameplay page, but will only be able improve the game after the Game Off voting ends in spirit of the game jam :)


A nice, entertaining diversion. Points off for realism though - pretty sure it's a little harder in real life to take over the world like that on as few kilobytes as that, ha!


love the aesthetic and the old pc vibe!


oddly addicting...


An absolutely fun little game, capturing some of the fun vibe from skynet simulator!

I certainly hope you keep making games like this!
