@artur0008: This game has patched 2x today. It is singleplayer and offline but uses il2cpp and encrypt values. That means it requires more work than most other games.
Popularity is just one aspect of many, not the only one. In the end we're doing a full time job and we provide a service. We need to make sure that we can pay our bills at the end of the month. If you cannot offer our membership, that's absolutely okay. But we also cannot give it away for free either, I'm sorry.
No worrys I understant atless I am useing the promo version to make the game speed higher
