Very addictive game
Northern Tale is a typical game were you need to find the perfect balance between time management & building resources.
Your aim is to get 3 stars for every level so you can unlock the bonus level. Some levels are more difficult than others & you need to replay some levels a lot to reach the 3-star goal. I didn't find this to be boring at all, on the contrary, it gets to be very addictive. If you are/get frustrated quickly, this is NOT the game for you.
Every level has more or more difficult tasks you need to complete to achieve stars and especially when not playing the multitask option of the game, you need to have eyes everywhere...
