Now to make things simple to understand, I have provided a little ref of the reason for each character. In the game, each character has a specific meaning, resulting in Satax's past. from where it first started to now.

Sonic's Meaning: Sonic's stage was meant to represent the realization of talk about him being deleted. Which is why Sonic's stage starts off normal until the very end of it.

Tails's Meaning: Tails's stage is meant to represent the plan with Kyle. as going through Talis's stage this shows that Satax is "chasing" you. but after you "escape" you come across a broken capsule. Which the capsule is the start of the plan.

Knuckles's Meaning: Knuckles's stage represents the fight with tom, as Satax was able to take control of all electrical devices and such in his room, tom fought back. But Satax making a fake loss. He ultimately tricked tom and killed him with an electrical blast. Something like an intense volt shock.

Robotnik's Meaning: Robotnik's stage was to represent Kyle going back and planning to leave. However, after Satax killed tom, he began to lose his mind, fighting with Kyle and ultimately ending up killing him by accident.

Metal's Meaning: after Kyles death, police was informed by neighbors, soon the story was hit all over the news. "Sonic game Kills Sega employee." Satax being nervous and scared sick, hid inside the games files to play as normal. until Sega was able to locate the virus and attempt to delete him. Metal's stage represents the race to determine SEGA's story. But in the end, satax kills of metal. meaning that Now satax has released the game, Sega's truth on what they do and did to satax himself.

V2 Majin's Meaning: Will be explained when v2 drops!
