Pretty good mod that's better than the base game in almost every way, although Sonic Forces was pretty bad, so that's not telling the full story.

I liked the story and was surprised by how much effort was put into it for a mod. They use comic book panels with voice acting for the cutscenes which was well beyond what I expected from a mod. There's also some original music that I liked here, and the final boss theme was pretty awesome.

The levels have a lot to them, and are pretty fun with how much they throw at you and how many paths you can take. But I had a problem with identifying paths and obstacles before they passed, and I think these levels can benefit from some better indication of stuff like that. But other than that, these were some good levels.

It's also worth noting that this took me less than 2 hours to go through, but I didn't go for all S-Ranks or red-star-rings, so there's definitely a decent amount of content for people looking for it. But the mod is pretty short if you just play through the levels once each, like I did.

Overall, if you have Sonic Forces on PC, and like boost formula Sonic, I highly recommend you give it a try.
