Changes in this version of the demo:
- Added the rocket, missile, laser, and machinegun weapons.
- Each pilot now has their own specific starting weapon, and this is shown on the pilot select screen.
- The level selection screen now shows the amount of time you need to survive for each level.
- You can now view scores for all available levels on the leaderboard screen.
- The fourth level now has different music. I plan to have different audio tracks for each level for the full game release.
