SEGA on keeping new stages in Sonic Mania a surprise, gameplay length, other elements teased

The following comes from Sonic PR and social media manager Aaron Webber...

- SEGA is showing more of the classic stages in Sonic Mania so that the new ones will remain a surprise for players
- SEGA doesn't want to spoil the entire game for fans
- Sonic Mania's length depends on how good the player is
- much like classic Sonic games, “if you’re really good” and “if you know all of the tricks, you can shave off a lot of time.”
- “it will still take awhile if you want to beat the game as Sonic, as Tails, and Knuckles.”
- “other elements” that can extend gameplay were teased, but not revealed
