Thanks for your help. I know I should be promoting the game myself, but I haven't had any success so far. I'd be happy if indexing brought me even a few new players.
Viewing post in My game is still not indexed after 3 months.
Yes, I tried Reddit; it's the only place that's given me anything. I got about 10 players and a few good reviews, but it's still very little. I think it's the game itself; despite its high quality, it's not a popular genre. I hope my new project, which I'm currently working on, will attract more players.
