Release date: We are releasing Beta 2.0 on Nov 22, 2013. The Beta 1.5 version live right now is essentially complete in terms of gameplay; the major change will be to the monetization system. 2.0 represents a switch from freemium with in-app microtransactions to a free trial/purchase-to-complete-the-episode model. There will be some UI tweaks in Beta 2.0, mainly associated with the new monetization model.
Please let me know if further information would be useful at this time. Again, thanks!
