Support has been backed up badly since spring, first due to technical issues, then to the BLM bundle. The situation is ongoing. Issues had to be prioritized.
Your game is perfectly visible in a search, and it had the normal evolution of most games, traffic-wise. All I can say is: watch your analytics. Revise your tags. See what you might have missed. Make your devlogs more meaty. Quality over quantity, because search engines index them. Speaking of which, don't neglect your creator profile either. It's by far my #1 source of traffic. Also, you don't seem to have a Twitter account (maybe for the best) and I don't remember spotting a mention of your game on the LemmaSoft forums either. For that matter, interact with people right here in the community, too, because that's how they hear about you. Hope this helps.
