0.1.2 - Improve My Game Jam #14 Update

For the Improve My Game Jam #14, I improved upon Stone Lake. Mainly just the graphics, as I had some things missing because Stone Lake was developed in 3 days at the time, and I had cut some corners. I wanted to do gameplay changes, introduce new mechanics and/or add new levels, but that'll have to be for the next IMGJam.

Changelog:

- Bugfix: Music no longer plays over itself when playing through the 4 levels and returning to the intro
- Graphics: 3D animated skybox
- Graphics: drone sights now have a texture instead of being one flat color
- Graphics: visual holes with spikes instead of having just a void you fall into, level 2's layout was changed very slightly to accomodate for the spikes
- Graphics: door textures rather than having a hole in the wall you walk through
- Graphics: one piece of vegetation in starting level (meant to do more but didn't get around to it)
- UI: Mouse sensitivity label
