Snakopid 1.3v

I took a break from my main project and made this Snake alike game.

1.3v

- Added Easy and Hard Mode
- Made some visual adjustments
- Optimized snake/centipede body logic, blocker spawning, etc.

1.2v

- Optimized a few issues (Blockers spawning on player now disappear, added more spawn points, etc.)
- Fixed issue where players could move before starting the game

1.1v

- Fixed an issue where, upon eating 2 or more "fruits" in a row, separates the body.
- Reduced the highest default score to 700 (Thanks, Joseph from Discord).
- Added "blockers" to game which can be destroyed with the body (rotating around it), but kill player if hit with head.
