[School Project] Platform Jumping Game

- Left and Right arrow keys to move
- Up to jump
Goal: Avoid the erasers and reach the door of every level.

This was made for a class project, there are a couple bugs I couldn't fix:
- When jumping, the player gets “stuck” in the platform (legs are “inside” the platform, but game will run smoothly).
- Music won’t stop playing (it starts in the Menu World, but the user dies in the Map world, so I couldn’t figure out how to access the sound).
- Greenfoot Gallery related glitch(?): When reset is pressed, the music may stop and not play again, the menu does not reload.

There are only 5 levels, so I hope I made them difficult enough..
