Cleanup code

[Herman1412]

We need to ensure consistent code conventions throughout the entirety of the project. The following conventions we will commit to are:

• [x] Csharpier code formatting
• [x] prefixes for private variables _ and constants k_
• [x] Use private [SerializeField] over public variables.
• [x] Fix comments in GutFish.cs
• [x] Optimize code
