Desert Zombies released for Android

Hi,
I finally completed my first game and it’s for android devices, called Desert Zombies :).
Desert Zombies is a casual top-down cartoon style zombies shooter. Shoot lots of zombies, collect dropped coins, upgrade weapons. Survive as much as you can and compare your score with online TOP 10 leaderboard! Oh, and be careful not to touch cactuses in hard mode!

Just logged into play store and this will install when I turn on my tablet, cant wait to play but its on charge at the moment.

UPDATE:
I played it on 10 inch tablet but the movement control is to close to the edge of the screen and my thumb kept going off the edge and so the character stopped and got killed.

Maybe move the movement control towards the center of the screen a bit more and make its touch area bigger (for those with big spoon thumbs)

Also I want a grenade to lob into those large groups of zombies that come at me, or a landmine I can place.

I like this game but needs more to keep people interested in it.

Thanks, I updated a little bit, so now joysticks are floating and not fixed.
