Planet Wisp was heavily industrialized in Colors, guys. If anything there is more wilderness in Generations.
The level's problem isn't the scenery, it's the overreliance on wisps, especially in Act 1. Act 1 is essentially a series of painfully easy but slow puzzles with very little real platforming. It's just not fun. What they should have done was design the level to be just like the rest and not used the wisps at all or if they did use the wisps use them sparingly and for normal platforming. Use spikes for navigation, not puzzle solving. Sky Sanctuary didn't have elemental shields; hell, none of the levels even had normal shields.
