Just finished 171, but haven't got energy to start 172... They were a really nice few levels! It was nice to have a breather after those fire levels! Felt like the earlier levels when it was fun!
However, 5 minutes on the clock makes me a bad mummy... My little person had to watch a few episodes of Sarah and Duck just so I could play (not that she minded of course!!)... Those levels with 9 minutes on the clock are going to be too long for me to manage...
