Thank you very much @NoTimeToPlay for fast reply (means a lot). I was searching for that exact query "game not indexed" and that post didn't pop up somehow.
Useful stuff, and I agree with all of it. Somewhere I read that it could take a few days but wanted to check that everything is okay on my side. I do have a website quite ready (I'm a backend dev btw), but since the game is still in-development practically and I'm starting to get some traction and first "followers" I'm still trying to focus on player feedback and it would mean a lot if the game is at least shown when someone enters it's name in the search bar. Now it says there is absolutely nothing when someone types the game name: https://itch.io/search?q=Izborna+Loodnica.
I'll publish some more screenshots after the next release and probably a short video but please let me know if there is anything more I can do about it.
