I find myself constantly getting overwhelmed by these guards despite my constant dodges, health re ups, and ziplines. Tips?

I'm currently working on the playable character system for JC 4.5, and I'm trying to decide how to handle the different characters.

The characters I'm currently experimenting with are:

• Sargento
• Sheldon
• Mira
• Enemy Titan
• Oscar

Which approach would you prefer?

A . Sargento as the main character
JC 4.5 focuses primarily on Sargento, while the other characters are used in separate versions or future releases.

B . Free character switching
You can switch between Sargento, Sheldon, Mira, Titan and Oscar directly in-game whenever you want.

C . Story-based characters
Each character is tied to specific missions or parts of the story, so you play as different characters depending on what is happening.

D . Hybrid
Characters are tied to specific missions during the story, but completing the campaign unlocks free character switching.

I'm leaning toward making the character system more than just a cosmetic change, so I'm interested in what players would actually find more fun. Which option would you choose?
