OFFLINE

I find games that request that I send annoying invites to my friends to be overbearing, and not worth playing.  I found out that I won't be able to unlock tanks, 3, 4, etc without this.  I'm deleting the Aqualife 3d app for this reason.  It was fun playing, but if I can't advance without irritating my friends and socially alienating myself, it's not worthwhile.  You will not get me back, and I hope this is a lesson for you on future game design.
