First the game runs on top of Mercury's 100%+ accurate engine AeStHete. That's a name you might want to remember because its a very advanced opensource Sonic engine that has yet to be released. More info on Mercury's Blog.
Now on to time twisted the game aims to grab the best elements from all 5 Genesis Sonic games to create the best Sonic experience possible. The game has a total of ten planned zones with a future and past version of each stage. Each stage also contain 10 at least semi-original gimmicks. Sonic, Knuckles, and Tails are planned playable and the story will revolve around UFO's, Time Stones, Chaos Emeralds, Robotnik, and Metal Sonic.
Hinchy's has been working very hard on a completely original soundtrack for the game. The album called Two Ages can be found on the Sound Track Website.
Thanks to everyone who is helping with the project.
