I'm very busy this weekend, so I will only be able to put in some hours to this, so it needs to be simple simple simple!

My idea is simple. So that's good.

I should probably spend some time picking a game engine, even if just doing it in VanillaJS is somewhat tempting. It does need to run on everyone's machines, though... Maybe the HTML5 option from Cocos2d-X... I do also have GameMaker Studio, I could use Unity, do something with Haxe... Options, options.
