Hey, i created a game a while ago (still updating it). It's a simple top-down retro zombie game, it has a scoreboard (removeable) and if you want i would love to update it every now and then, it has different weapons (you get them at a specific score). It's easy to add more of them. It's not made for phones but i could extend the game for Android (It will cost around $10 more). The graphics are not really good but they are easy to replace. I didn't add sound yet but if you want i can add copyright free sounds. I would like to get around $40 for it on PayPal. You will get the .capx file and i will explain how to add weapons (ofcourse i will remove it from my site).
Please contact me on skype or on my email (not on scirra.com)
