Hello everyone,
Don't scare, the game isn't abandoned. We are just migrate to the new version of Unity, which broke 75% of UI's screens. 2 month we are talked with Unity, has share with them our project sources and explain what happen and where the broken point, but they just said: "Ehm guys, we are can't help you with nothing".
So we are start to migrate all our's UI's to new engine version, that's why upcoming update is delayed and will be near of February.
