A few days ago v0.6.1 was released. It improves the handling of landscape mode and restructures the game menue. Important for me was also the integration of in-app purchases, specifically you can now disable ads by buying an in-app purchase via the game menue. It still has some rough edges (eg you have to restart the app after purchasing) but this has been on my list since the beginning. I will try to improve the flow in the next versions.
