Progress has been made, so why not do a little update?

- The Specter enemy has been moved from experimental to the main game! This means currently no experimental enemy is tested, but the seat won't remain vacant for long
- Quick mute music & sfx buttons added
- Removed the afterimage option, might add it later with the implementation of the particle option
- Small fixes & improvements to the game

That's all for now. Prepare for a boss next time. And with that, cheers!
