Some minor changes based on feedback received from MagWest 2024

- Changed 2-1 to be a little more forgiving, and added an alternative easier path
- Removed wall blocking players from using the red spring on the right-side of level 3-2, and added an extra platform to use
- Added death planes in tutorial, so players don't need to fall as far to die
- Fixed name of executable when viewed in sound mixer to be "Super Sushi Roll" and not "A 2D Marble Game"
