- No music and no Tails flying on the Pico screen.
- The title screen has instruments instead of music notes.
- There is a sound test on the title screen; pressing up and changes the music and pressing left and right changes the sound effects (up to 10 then silent).
- Some of the music is work in progress such as the firstst page has a telephone style ring on the track and missing instruments on Canon in D.
- There is a bug on the first page that if Tails moves towards the absolute left or right of the ground and keeps moving, he can moonwalk.
- Different music on the Stop command in the Green Hill Zone. Also the music doesn't start straight away when you start the level.
- The Wall of Music minigame (the Breakout clone) starts with four lines instead of one.
- The musical chairs mini game is only a test with one frog and Tails hopping with a number counter on how many hops have been done.
- Different Sonic sprite and completely different music on the fifth page instead of reusing the title theme.
