Game's Open Back :)
- Finally, game uses an official free chat api, which is the gemini-pro.
- Combats and so many things will be bugged for now, but finding an official free chat api was the most important thing. From now on, game will be maintained.
- Free plan of Google's gemini-pro chat api is generous enough for a forgotten application which will have chat requests lower than 60 QPM (query per minute), so we're safe with free gemini-pro.
