It's fun to play and an accurate representation, but from all the mobile games i've played, none of the controls are like this. I recommend you do a few things to the controls.
-Remove view acceleration. It messes up people who have played other mobile games.
-Remove the joystick for aiming. Most mobile games have no right joystick. Instead, anywhere on the right half or the whole screen in considered how you look around. It is used like your screen is a mousepad, and your finger is the mouse instead of using a joystick style where the more you move your finger the faster it moves.
-Add an interaction button. Now that you don't have a second joystick, you have room for an interaction button. It would be a static button that would appear when you are near something to pick up. It would be somewhere on the right side, and wouldn't move to be on top of the item unlike the pc version.
It's a good game so far and you have plenty of content, but the controls make it much harder to play.
