Я ведь буду прав, если предположу, что автор из России?
На всякий случай оставлю комментарий на ломанном английском:
This is really unusual. A non-standard gameplay that periodically raises questions in my head.
The author, as an idea: maybe you can make some small icon on the main screen, where it will be described which icon refers to what? Yes, the user will dig around for the first time, memorize the guide, but later it will be deposited in his head and he will freely and quickly weed out candidates. I liked it, even though I didn't play for long. I will definitely keep an eye on the future of the game.
Author, would you share the secret of where the characters were generated?
Good luck in the development of the project!
