I made a pc game recently (uni project) and now I want to put it on google market but I am having troubles changing original controls to touchscreen. The problem is that I don't really know what I can use for controls (tap, double tap, etc.) so the app is really easy to use. I will be incredibly grateful if you could share ideas for what types of controls can be used for my game.
The player controls a shield, which moves around the inner circle (originally the object follows mouse cursor). The player can also shoot with the shield to destroy obstacles, so the bullet is created inside the shield and then travels in the direction the shield was facing (the bullet is created on mouse click).
In the mobile version, the player controls the shield with his finger. It creates two problems: the player is not able to see some of the obstacles because his hand covers some parts of the screen. Also, it means I cannot use simple tap (or at least I don't know how) for shooting, which makes the controls unintuitive. To shoot the player has to touch the screen with two fingers. It is not a common gesture, so people won't think of using it straight away unless told what to do. And the main point of my game is that there are no words at all and people are expected to understand controls without any tutorials. Also, the game relies on quick reactions, so controls cannot be complicated. Thank you!
