This was a rad experience. Love these types of games. Really enjoyed the storytelling.
Also dig the art. Particularly liked the night sky reflecting on the water in the intro sequence. Created a very cool atmosphere.
On my first try, I almost missed that you could exit the cave again once entered, which is before a pretty meaty part of the story. Think it might be because there were too few art elements at the bottom of the play area to guide me. I kept trying to go deeper into the cave.
Also, you can exit the future/second version of the cave before visiting the objects, which I felt was quite a cool part of the narrative to miss (I accidentally walked out of the cave in one try).
I welcome the addition of Coco - it's about time Wilson had a bit of competition :)
