In the prototype of Sonic Spinball, there were multiple changes to the heading quotes.

Here, when Sonic has attacked enough point bonuses, it says 'Open Hatchways'.

The prototype does say 'How about a ride', when you slide down towards the sludge Drum, but it doesn't move the camera like the final.

Here's a comparison shot from the final game, where the camera has moved down so you can see the Drum.

The final game has the sludge smaller and more in colour with the surrounding goo.

In the prototype, these is an extra layer of sludge surrounding the bucket, or at least discoloured.

In the prototype, the Scorpius Boss can be hit by falling rocks, which can cause him to die without Sonic hitting him on the final blow.

Also in the prototype, when Scorpius dies, bits and pieces fall from him, but his body stays intact.

In the final, Scoprius blows into chunks until the head is left.
