Thank you very much for your feedback, I find it very interesting. The idea of the leaderboard is a good one. I hadn't thought of using the current day to define a seed.
Also, the idea of being able to continue playing after all the tiles have been seems interesting.
For the moment, I'm focusing on developing other games, but I'm keeping these ideas in mind.
Also, congratulations on making it in 10 days, I think my best is 12 lol
