It didn't feel finished to me - you could wander around the forest and interact with some stuff but I was never able to figure out what the "game" was. That might just be me, though - I'm not a gamer, really.
Note this was the old Blender before the UI rework and the game engine used here was removed from Blender. I believe the game engine stuff they have now is completely different code.
I bought the Apricot DVD (or was it a CDROM?) to support Blender, and I still have it somewhere. I think all the contents (assets) were also posted online later anyway. Game seemed more like a tech demo and it did not run very well at least on my computer back then.
Still like the old Blender UI, in some ways it felt less bloated and easier to use than the newer "friendlier" UI, but I am happy to hear they moved on to focus on Godot support instead of maintaining their own game engine.
