It's very nice made game but too slow progress at the beginning and 2x speed behind 500 gems wall will be the reason 90% of players won't stay playing past day 2.
Just give stat which increases active gameplay bonus which can be improved with anima points and problem solved with offline game being more rewarding than online.
We're currently working on fixing the offline/online reward issue. If you have some interesting suggestions please stop by the forums so that the rest of the community can join in on the discussion. Thanks for playing =)
I reuploaded the game as that seemed to fix this issue for a few people a couple of weeks ago. Sometimes kongregate or the browser caches things. Please let me know if this didn't help you.
No ads on Kong. That button is for mobile players.
