Found a couple issues with Nadine's Fleet II, so some fixes and add-ons were applied:

• Fixed the frame rate issue that could be problematic for Firefox 110+ users.
• Fixed the issue with the Round 11 boss, allowing the player to complete the entire game.
• Added a BGM track for the cave levels.
• Changed a few map tile placements.
• Added game controller support.
• Fixed a problem where the final intro cutscene would hang before taking the player to the title screen.
