Sorry if this is the wrong place to post this or if I'm even supposed to post this. There is a live wallpaper called pixel zombies that I believe if something similar like it were made into a game and there were some additions to it(powerups/weapons) it would be a pretty fun little arcade type game that I would most definitely buy. How hard would it be to create a game like this though? I'm very new to android in general and developing anything and don't believe I would be able to create something of this degree. Would any devs out there be down for making something like this because there is , in my opinion, a lack of any horde/zombie type game that's even halfway decent?

Thanks.
