Patch 1.4 - Small fixes and changes

I am currently working on adding Episode 3 to CARNAL, but thought I should maybe just upload a patch to fix some of the things I received through player feedback.

Changelog:

• All enemy projectiles move at a much lower velocity
• Most enemies now have considerably lower health
• Fixed player sliding down sloped areas or inclines.
• Added an SFX slider in the Settings menu
• Game will now save all volume settings

As always feel free to ask any questions or to give feedback, I appreciate you guys for trying out the game. More levels coming soon!
