Thank you for playing and the suggestions!
Saving will be added at some point, but I'm still new to the Godot engine, so I need to figure out a good way to do it that will ensure compatibility with updated versions. I may just add a small warning that the current version does not save somewhere.
I was hoping that the speaking animations would help players understand who's talking at a glance, but unique dialogue name colors is a good idea to help with that.
I tried to keep the expeditions short enough not to feel like too much of a setback if you fail. I'd like to add more consolation prizes for partial completion. Right now you get xp for your shop to unlock new prisms and expedition options, but I'd like for to offer some permanent upgrades in the future too.
In the patched version that I'm working on right now, I'm introducing silhouettes for things that are just a bit beyond the range of vision to help players plan their exploration routes.
Sorry about the current lack of saves, but I'm happy that you had a pretty good time regardless!
