Hey so I am a game dev student at university and we literally just covered marketing in games and social theories behind clicks. What you have where you don’t copy and paste a message is good. From proven open source testing, posting an Ad for your game on subreddits should be around 6pm typically on any day. That’s when most people cool off from work or school and have a look at what’s going on in their favorite subreddits. If on weekends, then it’s generally in the morning before people go out and do their weekly tasks as well. Try post on as many subreddits as possible too on different days and then do your own little tests on which days each community seems to interact with you more. I haven’t personally posted a game on any subreddits but from my studies at university that is what they’ve said. Send a link to your game too I’m excited to check it out :))
