Sorry, but the author of the GA does not want to say what game is inside yet. Therefore, I also have no right to do this... 🙁

I can tell you one thing - the GA will continue for another 17 days, during this time you can manage to solve this puzzle. Even if you'll spend 10 minutes a day in the evenings.
And maybe later the author himself will say what kind of game is inside 🎈

The maximum solution time is 2 hours for those who do not know how to collect puzzles at all.
I wish you good luck, you can do it! 😊
My advice is to start with bright colored pieces and then connect them. And of course the borders. Like here:
