Thank you so much for playing the game for so long and writing such detailed feedback! Im really glad you enjoyed it, and its great to hear that you would even consider buying it. For now I am planning to release it for free on the Google Play Store and it will always be free on itch.io too.
Your feedback about the confusing parts and the overall pacing is really helpful and I will definitely keep it in mind for future updates.
About the situation where all the neighboring countries had the same color, I think that was a rare event where a huge alliance forms. Theres a small chance that alliances like nato, brics, an Asian alliance or an African alliance form during a game. Be sure to keep an eye on World News for that.
For random events theres always a chance that your decision can backfire, even if it looks good at first. This is intentional so theres not always one clearly right choice, but I will take your feedback into consideration to make the outcomes clearer.
I will definitely add the ability to send more troops into a country while an attack is already happening, thats a great idea.
Thanks again for helping me improve the game :)
