The second fruit (Either cherries or blueberries depending on the version) increased from 100 to 200 points in the final version.
Apples are worth 200 points in the prototype, 500 points in the final game. In the final game, the player can also press the Shot button to stop hanging. In the prototype, if Mickey is hanging from a ceiling or block, the only way to get him to stop hanging is to hold down until his rope is exhausted. Mickey can't climb up grey blocks in the prototype. Even if energy is set to 0 through RAM manipulation, the costume will function normally. The Mountaineer costume has an energy meter, but there's nothing in the game that depletes it. In the final game, running out of energy will only let the player shoot a single short spray of water. Running out of energy in the Firefighter costume will still let the player spray at full blast in the prototype. Thankfully, the Wizard outfit got a new ability: A protective bubble that provides air while underwater. The final game adds an invisible oxygen meter if it depletes, the player will start taking damage. In the prototype, the player has infinite air while underwater. Once the player regains control of Mickey, the magic snaps back to Mickey's finger. If the player is hit while charging in the Wizard costume and keeps the Shot button held down, the magical energy will stay in the same place it was before the player got hit. To show off how the costume system works, the player starts out with all three outfits. It seems that someone on the development team was nostalgic for the old system the old control scheme appears as a setting in the Options menu in future games. In the final game, the player only has to press the Hold button once to pick up an object and press it again to throw or spin it. In the prototype, the player has to keep the Hold button held down to carry objects, and release the Hold button to throw/spin them.
It takes slightly longer to go from walking to running while on a sloped surface: 20 frames in the prototype, 12 frames in the final version.
