Linux version

Added a linux version for this week. I tested the mouse and keyboard version and that worked fine but due to my headset I can't test the VR version. Let me know if there are any issues with that.

This update also brings changes to the way fishing works. The previous one was okay for mouse and keyboard but worked quite badly for vr so right now I am moving towards a system that works well on both while still taking advantage of the unique controls that a vr set brings. 

For next week I plan to add general updates across the board, with new dialogue and improved fishing.
