Last minute polishing for LevelUp Showcase:

• update graphics and animations for healthbar, pause screen, character, effects
• adjust difficulty and make player meet notes to  hit it (as play testers were doing this instincually)
• fix score calculation and presentation and end of game (D, C, B, A, S rank)
• Fix sound effects

Planning non-game related things for showcase (stickers, snacks, trailer, etc)
