Model updates

I just pushed a new build with some newly created 3d models. I did all the modeling and texturing myself. I'm pretty happy with how all of the artwork came out.

Changes:

• Added new 3d environment art in all of the levels 🌎
• Added tiling materials on the walls and ceilings 🧱
• Optimized unity's hdrp render pipeline options 📷
• Replaced first person view hands with actual hand models  ✊
• Lots of little bug fixes here and there 🐛🐛🐛🐛🐛🐛🐛🐛🐛

Next update I'm going to be tackling the combat system and continuing to stomp bugs as I see them.
