Hello everyone, been chipping away at Zombies!!! Run!!! for a couple days. Replaced some of the dummy art assets with something better, and tweaked the gameplay a bit - added a distance counter and a score counter (but no weapons or pickups yet so nothing will increase your score in this release)
You can now move up and down using the up and down arrows, and your character will snap to each of the 4 lanes. I found it was easier to do collision and z-indexing this way, and its easier to judge if your character will hit or not. The characters hit-box is the shadow at his feet. I've got my daughter on my lap as I write this, so I'll update with more info later. Have fun!
