After first launch, disappointed. not because of the result, but because of the doubt

I made some public post abt my project at Reddit. 150 views, 0 comments.

Of course I never expected my product to go viral in seconds and went boom. But one thing is catching my ankle. It's not this 'unsuccessfulness', or 'indifference' but it's the concern that I might be holding on to something that wouldn't work. Guess theres only one way to find it out.
