Update main features and minor bug fixes

Hello dears!

Here at Tmesis Studio we are working for you ;)

While we're working on the full game, we're adding some general features to the title.
We wanted to implement what we could in the Prologue, thanks to this update.

- Custom cursors on possible actions
- Improvement of overall performance
- Standardized camera movements
- Fixed minor and non-impactful bugs

Enjoy!! ;)
