The Snails were replaced by the monkeys.

Robotnik's car explodes almost like in the final version. The difference is that if you destroy it when it's facing left, it turns to the right when Robotnik escapes.

There are no enemies but the blue worms.

The graphics at the loops are like in the Beta 1.

It might be just like the complete version.

Same traps of the Beta 1.

They changed the switches to the final hanging plants.

It was said it had the final enemies, but I haven't seen them.  It's possible because there's a 100 points difference between the pictures S2B2-37 and S2B2-37.

It's the same demo at the Beta 1, but because of Tails' different behaviour, he gets one more ring.

It's like the Beta 1 2 Player Mode.

There's a Sonic lives counter where it's supposed to be the Tails'.

When Tails dies, he appears at Sonic's position.
