Looking over the maps again and again, and crosschecking with the known prototype builds, I have a level order to to suggest, with tentative music selections based upon theme, progression, and known placements within the Simon Wai beta in particular. I could very well be wrong on the associated themes, but I feel fairly confident at this time with the level progression. Note that i did nix the medieval period considering how there was no map to work off of. Present: 1. Green Hill Zone - Emerald Hill 2p 2. Ocean Wind Zone - Carnival Night 2p 3. Wood Zone - Metropolis 4. Sand Shower Zone - Mystic Cave 2p 5. Metropolis Zone - Death Egg part 1 Ancient: 6. Rock World Zone - Game Results or Wing Fortress? 7. Tropical Plant Zone - Sky Chase or Metropolis? 8. Hill Top Zone - Hill Top 9. Blue Lake Zone - Aquatic Ruin 10. Olympus - Hidden Palace (Sound test 10) Present Bad: 7. Rock World Zone - Mystic Cave 8. Oil Ocean Zone - Oil Ocean 9. Dust Hill Zone - Emerald Hill Future: 10. Casino Night Zone - Casino Night 11. Chemical Plant Zone - Chemical Plant 12. Genocide City Zone 1 - Wing Fortress or Sky Chase? 13. Genocide City Zone 2 - Death Egg part 2 I concocted the zone order based upon the flow of the maps, with keeping in my mind where Sonic would end up during timelline transitions. I anticipated that Sonic would not always be traveling in the same direction. For instance, after some time shenanigans upon a presumed battle with Eggman at Metropolis zone, Sonic would be thrust right in the same location, only then known as Rock World zone. From there he works his way up the mountain, and down the falls to Olympus. I am equating Olympus with Hidden Temple, and that may very well be wrong. Time-traveling up from there, he gets plopped into the mines of Rock World Zones new present, which I am inclined to believe would be basically Mystic Cave Zone. From there he runs through the Oil Ocean facility (soon to be CPZ), until he reaches Green Hill Zone, only now its Dust Hill. Somehow he ends up in the future from there, working down from Casino Night to Chemical Plant, and finally the Genocide cities.
