Loved playing this game until the latest update. It was the only game that I bothered to buy the ad-free version for as it was that good. The latest update requires watching 4 ads to get an additional tube instead of 1. This wouldn't even be so bad if they were short ads but no - they are the longest ads I've come across, some being at least 45 secs or more. The game is now unplayable so I've stopped playing. Developers, you now are getting no income instead of some from me. Bad move?
