For this type of game, and the long term plans we have for things, a traditional premium version model just doesn't work. Especially with the event design, and the fact it'll be incorporated into the Apple leaderboards.
We are, though, as mentioned above discussing a variety of options to give you the best experience and use for the different coin options available. As many F2P games have found it takes some tweaking after release to find that sweet spot in design to give you the best balance. We're listening to everything you guys say, and discussing it to find that spot for FOB!
So stay tuned!
The controls are extremely solid once you get used to them, and tweak the gyro sensitivity to your personal play style. I love it as well!
