Universal Coin and Madhouse Mode Unlock

Includes the following:
- Universal Coin
Keep this in your inventory to get a slight boost to your attack, defense and knockback rate. The coin is added to your item box, and can be used in both the main game and the Not a Hero free additional story chapter. Holding multiple coins will increase the effect.

- Madhouse difficulty level unlock
Unlocks the insanely difficult Madhouse mode, which normally only becomes available after completing the game.
