Rabbits are dear to me and so I was keen to have a go on the DS Bunnyz game.
Overall, I quite like it. You can choose from a selection the type of bunny you would like to have, name them, and teach the bunny words to say. You need to keep the hutch clean, brush and pet the bunny. Additionally there are games to play in order to win further food, water, treats, toys and different hutches for your bunny, even little hats and things! You can take your bunny for a run outside the hutch and pick up little gifts from time to time. Also I believe you can interact with others who have the game.
There are several little games and they come up to be played randomly whenever the bunny says 'Play With Me!', and there are different levels to these games, none are very complicated. There is not an awful lot involved in using this game though, and you cannot choose when to play the games, they just come up every now and then.
I think this game is fun to play for a few minutes each day and is not demanding. If you are looking for something to keep you very busy and playing a lot then maybe choose something else. This is maybe something to have alongside other games you play too, which have more action involved.
