You will not be able to find people who have information related to your game on anonymous forums unless it is a very famous game already. You can't just go on /v/ and ask "hey guys, I got stuck in this recently released not very mainstream game, how do I progress", 99% of people there never heard of that game at all, and 99% of people who know the answer to your question will not ever see your question because it will be flushed in a day. Going on discord or reddit has higher success rate. Situation is different if that game has a thread dedicated to it for at least a few months or years, and a group of people who check it regularly, one of the chosen 100.
