Ads oh my god the ads. Sure they were short but dear lorde. I managed about 5 minutes of play time before I gave up. Edit - your app may be free from ads, but lets look at your current reviews which are negative almost entirely about your ads. I lasted 3 ads before uninstalling, maybe people last 10? or a little more? if you reduce ads people will probably watch 100 more if they are interrupted less as they will play more and enjoy the game. i know this, because i have watched way more then 3 ads in many other games, because they only pop up - on death or new games, or for bonuses, etc. you will get more ads watched if you make individual people experience ads less.
