#stonewielder

Chapter 1 was divided in half for some reason, with the second half starting after the twins fall into the chasm

In Chapter 2, the twins deflect a laser beam and destroy an entire star.

In Chapter 2, after destroying the aforementioned star, a monster made of triangles has a short monologue about the end of life on their planet. The monster (dubbed Morgami) then turns into a tiny triangle to wait out their inevitable demise.

Also in Chapter 2, the twins give Stonewielder an extra pair of legs that they just so happened to have on them since he never had any originally.

Let's just say there's a reason nothing of note happens in Chapter 3. You do not want a repeat of what originally happened in that chapter.

Originally, in Chapter 4, Stonewielder had managed to build a contraption that looks similar to a boss from the original Sonic game.

Also Stonewielder never got a cool staff.

In Chapter 5, Stonewielder gets knocked out by a lavaproof hamster ball and the twins never notice he's there

In Chapter 6 the Scourite is originally just a weird orb with an eye resembling a cat's. Additionally, we can see multiple of them.

Also in Chapter 6, there was no actual reason for the ship being there. It was also originally named "Prime Core".

In Chapter 7, the Savior just kind of showed up recently. Also, they were called the First Manifestation and trapped the twins in a simulation that they then proceeded to break out from using a pair of scissors.

One more thing of note regarding Chapter 7. The chapter was split in two. In the first part, the twins don't actually get the shard but are instead told to seek it at the Savior's Citadel, which is stationed off-world. In part 2, they enter the Citadel.
