Definitely need more context to better answer this.
That said, with only one or two endings and even if there's a lot of choices, that normally means your choices didn't have much impact because you had the same result anyway. You add more weight to decisions by leading people down different pathways. You'd likely want to branch it out a little more and write some what-if situations if people did this or that, which can lead to a different end result.
If a decision naturally leads to someone losing, then that's a good place to let the game end and potentially toss in an epilogue. Some people will put a lot of time into losing pathways, just to make those endings more satisfying. Regardless of how strong the writing is, if it's too linear then it half defeats the point of writing a CYS in the first place. The endings and the journey to get there go hand-in-hand.
