General:

- Star Coins have been added! Each time you collect one, after the battle you receive five coins for each one collected. Be careful though, if you lose the battle or exit, you will not keep the Star Coins. You need to win in order to obtain them.

- Wario and Donkey Kong have been given the items mechanic. The mushroom heals 5 HP each.

- Bowser's animations have been improved and sped up to make him feel more fun. His battle is officially complete.

Donkey Kong/K Rool:

- DK's third attack has him take out his coconut gun and charge it up. The more the charge, the more damage dealt. Too much charge, kaboom.

- If K Rool is defeated once, he'll get back up and try to defeat you as his last stand.

Peppino/The Noise/John:

- Phase 2 has been improved. Noise will look back at you and throw either a pizza slice or rock at you. If time runs out or Noise escapes, you lose. Use the boost pads to catch up to him and win.

- John will now spawn Noise and Pepperman to assist him in his challenge. Noise will throw pizza slices at you, and Pepperman will attempt to shoulder bash you three times. You have to hit him to avoid him.

Sans:

- If Waluigi successfully gets a hit on Sans, his heart will break and you get a game over. Listen carefully and press the space bar when you hear a swipe.
