Sometimes you just gotta take a DEEP breath and take the plunge. Our most recent game (SYSTEM//PURGE) has undergone so many iterative adjustments that I didn't think I was ever going to actually hit that big 'publish' button, but I'm glad I did, because within 8 hours I got my first 2 sales with the ONLY advertising being in a single subreddit - as of the time of this post the game is now on the "Top Selling" page, with a CTR of around 2.5% The REAL test is going to be from tomorrow, when the big Black Friday sale starts.
Best of luck and regardless of the final result, hold your head high - you did it. You put your project out there.
