Basics of game:
Zombie defense game where you are in the middle of the screen and zombies come from 4 directions (Upper left, lower left, upper right, lower right). You touch/click on 4 quadrants of the screen to shoot at zombies coming from that direction. Before shooting player moves to designated spot for that direction, as you can see in the first gif in the first post. The movement, opposed to standing in one position, can create a bit of strategy as more moving less time firing.
The player will be in some kind of light barricade, as in like a waist high 'wall'. Zombies will take a little time to climb over, but obviously you know what happens if they do. Probably add a melee attack for killing zombies against/on-top-of the wall.
That is basically the gist of the initial goal of the game—pretty simple and straightforward. Once that is perfected I can think about adding different weapons, enemies, locations, leveling up, exploration/scavenging between waves, etc—but that is definitely outside the scope of the initial goal.
Thanks,
Next up: will post a screenshot of some events and quick explanation, for those interested
