I will add, since the MC has the option of responding with Y/N being able to have an impact on how her actions play out and kind of helping (or) sabotaging her, could be really fun. This would probably add a lot of work though, but just a thought for later stages of development.
For example, maybe when her swimsuit gets snagged when trying to fit through a gap, you can choose to have her try anyway, ripping it and giving her some kind of debuff. (enemies are more aggressive etc.)
Same thing for the diving, like maybe you get punished for pushing your luck too soon and trying too many times on a low percentage dive and she gets slower movement for a bit or something since her lungs would take a hit.
I just hope there will be more player agency in how you can choose to approach each run, and what choices you want your salvor to make. This would help replayability too i believe.
