update - decided to play after a year break due to NO upgrades and last 3 times I have played there habe been forced ads! if they continue - im out It's great that you are doing updates but it would be amazeballs to have a new world or even just when it's to be expected. Many people have commented saying it's been over a year and the updates are just constant repeats. Would rate you much higher but sadly I am getting bored.

Repetitive and Boring. You get 4 to 5 adverts when you start the game each time. Amazing for the first 2 minutes and then it's more of the same with little stimulation. Ads come on just as you are to achieve a catch of a large creature. Then you lose it. What a sham..
