New Retro Rocket Revolution patch released!

I've pushed another patch, addressing some observations and bugs.

Bugs

• Fixed "janky" behaviour when the player hits the sides of the play area when using mouse control.
• Multiple resolutions should now work without losing visibility of menus or the play area.
• Fixed a bug where the background music would not loop.
• Fixed a bug where enemy ships and enemy bombs don't have any sound effects.
• Fixed a bug where enemies could spawn in the game over / high score screens.

Gameplay Enhancements

• Enemy bombs fall a little quicker.
• Added keyboard and gamepad sensitivity sliders in the game options that allow you to fine-tune movement with those control schemes.
  
• Selected control schemes are now "remembered" for the next time the game is launched.
  
• "How to Play" now has "Bonuses" and "Objects" screens, with better info on bricks and other game object types.

The patch is currently for the Linux and Windows versions at this time. I'm still improving the mobile experience and will post a separate patch for that when it's ready.
