The only person to judge if you made a mistake is your future self. Keep up working, continue making games, and if you need to return to the job market to have revenue temporarely or if you need to leave it on a shelf forever it doesn't delete the fact that you did a game.
I get it, the revenue is paramount, but the feeling you had doing it is also priceless. Too late for remorse anyway, go forward no matter the direction.
