nice ideas thanks for sharing.
i havent really attempted any marketing beyond reddit posts. i dont have social media either.
having one of my games included in the excellent indiepocalypse anthology helped me out in the beginning.
I just keep making stuff somehow im getting between 50 and 100 visits per day.
however, when im ready i will consider marketing and always interested to read peoples experiences.
for anyone starting out, i recommend Reddit. solid, easy & free way to share your work. great community too (opinions may differ on this). You can make some nice overlaps in the subreddits. i.e. i share some of my music apps to r/ambientmusic etc
If im completely honest, ITCH.IO in itself has been the best thing for me. great site with nice tools for sharing your projects. It has become the heart of my operations. I LOVE IT. the site and the people. oh and of course the jams... thats a nice way to make something and have fun with a like minded community. I would be lost without this site.
