Controls don't work; glitchy
The controls don't work. There is no way to point your weapon up or down. You can only point it left or right and even that is very slow action. There are no instructions. When I tried to navigate to the menu, the app became glitchy and it caused the cross hairs to bounce around. When you click the cross hairs, there is no way to back out of you don't want to fire after all. And once you fire the gun, if you miss, the game essentially seems to start over instead of reverting back to trying again or causing the enemy to run over to you.
