0.1.2 notes

- Added 'pause menu; Allow users to change controls between 2 keyboard setups.
- Added a double jump level.
- Adapted unity's new input system; most controls are adjusted following v0.1.1 controls and metrics.
- Adjusted movement and wall jumping controls.
- Added a timer for mechanics control testing level; just for fun. Test to see how fast you can clear the level with the mechanic controls i.e., wall jumping, double jumping.
