I actually played part 2 first, because I'm weird like that. This one is much shorter but equally entertaining. A couple of parts had me stumped as you have to say exactly the right thing, which isn't immediately obvious (the tree bit), but got there in the end (with a little help from XanMag!).
Absolutely brilliant. Very tricky in parts but logical. Great support from XanMag also when I hit a few oddities. If I could give it more than 5 stars, I would!
