If you look at successful entrepreneurs (or basically anyone who has gone the less ordinary path and reached some level of success), you'll usually see a list of failure or at least non-successes prior to the success you see them enjoying today. Same goes for artists and entertainers who become "overnight successes". It wasn't overnight for them! So you've done good work and gotten not the return you expected... it might take one more game or 10 more games. Or this game might lead you to meeting people that can help you be more successful in the future. It's ok to "give up" and move on too. You can stay the course and probably eventually become successful, but if you have other interesting things to do and less interest in continuing gamedev, then go try something new.
