If you were interested in trying this early, you can try it on - just … bear in mind it's no where near done. I mean, I don't even really think of it as "started" yet, barely worthy of an "alpha" label, but I digress.

Right now, it's just the overworld map, and clicking a tile will take you to a stage, where four random survivors will fight with a bunch of random zombies. If you're feeling particularly adventurous, you can open up the javascript console in your browser to really see what's going on.
