Just made an update to extend the gamepad support. This update brings following functionality with respect to the gamepad.

1. Menu Navigation is now possible using D-Pad, start and back button on the gamepad.
2. You can browse the levels and load the levels
3. Game can be paused and resumed using start and back button.

The default controls for the gamepad are as follows.

//Change the game pad controls here //Player movement is fixed to Dpad and Tunning blade direction to stick //Available values : A;B;X;Y:left-trigger;right-trigger;left-shoulder;right-shoulder { "Shatter":"left-trigger", "Attack":"X", "Jump": "A", "Sprint": "right-trigger", "weaponchange":"B" }

You can edit these controls as you like. The game pad config file is present in the game directory config/xboxcontroller.cfg

Note If you have already edited this file then after the update your file might have changed, please make sure to restore it back to your preferred setting.
