The game is quite nice to look at and is fairly fun to play as a rather short and very casual game. It's definitely geared toward kids and if there were no combat it would be perfect for extremely sheltered young'uns -- though maddeningly twee and boring for adults. Without combat it would be mind-numbingly dull.
Combat is very simple, you choose your weapon and click on the enemy and it auto-fights for you. It has a very basic skill tree where you are able to choose if you want to put xp points into weapons, or into passive skills or into other benefits.
There is no voice acting, but there's reams of reading between conversations you have with other characters and in books you find. If there had been voice acting I would either have been telling the screen to shut-up or skipped all dialogue options about half way through, so no voice is a positive rather than a complaint.
There are a number of different puzzles you have to solve to advance, and if you play a lot of puzzle games you would probably find them easy. If you don't, then a couple of them will be frustratingly difficult. Kids will probably need help with several of them.
Most of your time in the game is spent looking for plants to pick and objects to pick up, many of the latter are hidden under or behind furniture which you are able to drag out of the way. You can craft simple potions and a few weapons once you find or buy 'blueprints', as well as being able to buy what you need from several vendors. Overall, the game is a really good training RPG.
I have one big complaint about the game though, enough of one that I can't recommend it. The game makers want to share their love of God with you. One of the hidden books you find in the middle of the game, if you are a diligent searcher, has the entire Old Testament in it with the disclaimer that you aren't expected to read it if you don't want to but the Devs need to share their belief. After that, the amount of times your character is told to pray because of danger is infuriating. When I buy a game, especially a fantasy game, I am not paying for the Devs to evangelize at me.
