Zombies Til Dawn
Zombies Til Dawn is a turn-based strategy game where the goal is simple. You must survive until dawn. Your means of survival is in surrounding yourself with explosives and hoping that the zombies get blown up and don't get to you.
I kept a log of all the time that went into the game, and it totals at 13 hours, 13 minutes, and 13 seconds... yeah, lol it surprised me too.
I opted to avoid the use of any third party libraries. The game is made with pure JS, and should run equally well on all platforms. I've tested with my desktop in 3 browsers, and my android phone and tablet. I'd love to hear if the game works or does not work on your iOS devices or your browser.
