- Fixed a bug with the .html file missing the space.js file causing the game to fail to load
- Menu screen now properly references space.js
- Removed ocean.js and ocean.js.map as they serve no purpose to the game (previous from boiler plate)
- Added PLAY_EASY, PLAY_MEDIUM, and PLAY_HARD states to the constants file to be referenced
- Play Again on the GameOver screen now properly checks for the last chosen difficulty
- Implemented the images for the difficulty buttons
- Added play_easy.ts, play_medium.ts, and play_hard.ts as the difficulty states
- Fixed a bug where elements of the screen were visually gone but not actually gone causing the player to collide with nonexistant enemies
