Working Change 10 7 2021

This is a quick update to the game:

In addition to some changes to the general code and small tweaks to enemies, there is an entire new biome: the pirate cove! As reach the end of a level, there will be two exits and (at least this is what I plan for) the first level always goes to another level of the same biome, but the second and third have an alternative option and fourth level only leads to other biomes. This isn't as well observed in the newest build of the game but the mechanics are in place for when there are more than literally two biomes in the game.

The environments themselves have little to no mechanical differences but the enemies are different and I plan to add more in the future:

- even more enemies

- special sections of tunnels for special events

- special "quest"-like objectives to go through in tunnels

- more biomes
