V 0.0.3.1 Hotfix

This update addresses some of the bugs. Mostly minor tweaks but should greatly improve the experience:

Bugfixes/Improvements:

• Mouse is hidden during gameplay. For a better experience, mouse is now not shown, this was previously visible in the prototype for testing purposes but now fully works with UI.
• The fissure and rock throw ability were not doing damage at all. This has been fixed.
• The menu and spellcasting inputs weren't very responsive previously, hopefully now it's much better.
• Added an exit game button (can access it by pressing escape[menu])
• Fixed a bug where pressing the continue button would cause the next exit menu press to not be registered

Thank you to all the feedback given!
