First game update!

First update of the game! I took the feedback and corrected some things:

• Brand new menu: added several menu options and settings:
  • Pause menu and buttons
  • Game settings: include mouse sensitivity, timer and difficulty
  • Audio settings: for now only includes master volume
• fixed minor bugs related to UI

There's a lot of work to do: I want to remake the GUI, add visual cues around the treasures, and rethink the sound system. There are some cool stuff I want to add too, but for now I'm focusing on the feedback, so as always, any feedback will help me a lot! :D
