It's giving TUNIC if it was 3D Zelda instead. Very inspiring game in the vein of mixing metroidvania and metroidbrainia, with the whole 0% challenge informed by knowledge from the 100% challenge. The world feels very well realized while remaining compact, pretty much spot on in terms of scope for this context I think. I'll be revisiting this to take notes on this type of structure, it really feels worth exploring off of this example alone.
I personally have completed 56% and 6%, but I'm getting some leads out of talking to a friend as well. I think it's worth pointing out that this game, while perfectly doable alone, inspires conversation, and that's commendable in its own right!
