This is quite well-made indeed. It really tells a story and the mechanics behind it are amazing and very smart. Going 'inside' and 'outside' a house by a teleporter, flying around in a ship, multiple endings even? (I think I got a pretty bad ending...)
If there's one thing that would make this experience better, it'd be the addition of more details and improvements to the landscape and houses etc.
But I wouldn't worry too much about that, several adventure maps have completely spoiled me.
Oh, and the start, with the ducks... felt a bit weird and out of place.
"You're about to start on an epic journey... but first, here are some ducks to crash into!"
But I always keep some items on me to avoid annoying situations evil map makers created for me, so no harm done.
Cheaters DO prosper!
Anyway, I recommend anyone to give it a try!
