Here's a handful of situations where accurate whip-swinging is pretty neat:
- In the Greece-like stage, a single bone dragon drops big hearts into oblivion, unless you use whip-swinging before killing him to reach a platform below the dragon and whipping him from there.
- The Treasury stage is full of areas only reachable by whip-swinging, for instance, the part where you need to do 3 perfect swings to get a Holy Cross and lots of goodness.
- The room with the giant chandeliers, already awesome, also has whip-swinging bonanza.
- The spinning room (more Mode 7 eye-candy than anything else) where you are attacked by Medusa Heads (this is actually very cool!).
- The Clock Tower is a house of whip-swinging madness, with moving points for hooking and enemies attacking relentlessly.
- The Tower where you are chased by a giant cog has its share of whip-swinging dementia, with a Metroid countdown flavor.
My only complaint about SCIV in this regard, is that they designed no boss battle with the whip-swinging mechanic in mind. For instance, OoE has DAMNED GOOD fights involving the Magnes glyph, while using it for other purposes is kind of meh.
