BloodHunter V0.4

For this redo of the overall game I updated/created the following things:

- Created Custom pixel art for all assets of the level to create better consistency of the game. I hereby paid attention to keeping pixel size the same.

- Improved screen shake effects and added sound effects for player landing.

- Updated some of the sound effects to fit better with the game.

- Added a pause screen to allow the player to pause the game with escape. No other functionality is currently present in this screen.

- Slightly adjusted colour grading of the level to look better as a whole.
