0.1.1 -> 0.1.2

Actually application of bug fixing already detailed in 0.1.1 version release.
"The flashlight convering UI" bug was deeper than I expected (in the game editor, in Unity, it seemed fixed, but the problem was still present in the builded version).
Also the "Audio sliders not intercetable via mouse" problem has been fixed in this version.

Below, some Enhancements:
- Difficult increasing: now all the levels, for each character, implements difficult increasing parameters (enemies and rooms behave consequently)
- Flashlight difficult introduced: another level of difficult applied from character level 4 onwards has been introduced.
- MiniGame final UI removed (faulty UI).
- MiniGame rewards are now betters visible.

I'm still working on the game in order to implements all the features that I have in mind and fixing whatever doesn't work properly:)
