obligatory list of similar stuff.
- alba: a wildlife adventure. more gameplay but somewhat similar controls/feel
- a short hike. isometric but similar feel (thanks thrance)
- the legend of zelda: the wind waker. haven't played, but mentioned in a few other comments
- proteus. first person and more subtle gameplay
anything else?
If we're going off vibes alone, I believe "A Short Hike" would be closer.
yes, thanks! i was unsure whether to include it because it looks quite different. but you are right, it has the similar exploratory vibe and is a great game.
