Rhiannon gives you quite good value for you money being a first person point anc click adventure game. The rather spooky setting works quite well and the backstory is indeed interesting. Puzzle wise it's not overly hard, but not overly easy either.

he game does provide a good atmosphere and is worth a play if you're into horrorish point and click adventure games. I had some fun moments with it.

It's not the best game in the genre but it is decent, and the celtic setting is quite fun. Reminds a bit of Barrow Hill in setting and execution.
