Hello,
I've been playing the game and its awesome!
I'm at the world 5 - Lab of the fusionist and the bug is more than just the music not working. If I go to the last check point and die to the boss, then the check point does not work. It enter the stage and the character does not appear.
Another bug is in the World 6 - Treasure trove cove. The Banjo Kazooie stage. The letters for the puzzle of one of the jigsaws does not appear. I cant pass the stage.
