General Differences

• No copyright and date screen.
• You can skip Options if not on the title page.
• The music is at a lower pitch and has slightly different instruments than the final
• The message says Let's go next floor! instead of Let's play a game!
• Robotnik is mis-spelt as Robotnick throughout the game.
• The message says Have you played Sonic's Toy Grab? instead of The Toy Drop is fun!
• The casino floor from the Japanese version is still there but glitched with a graphic of Robotnik's name on and unaccessable.
• The list of characters after the Diamond Maze game haven't been implemented yet.
• There is a delay between revealing the contents and controller the character in the Diamond Maze. The mini game is also harder due to this.
• There is a message if Robotnik won or lost (I won!, I lost!) that is not in the final.
• The drawing page hasn't been implemented yet.
