Ultimately, if it stops here with development, all I can say is you did well and thanks for the work you did with it. If you feel like working on it more later on, that'd be cool but you do what's best for you. For a $5 game, it delivers really well. You did a good job and should be proud of your accomplishment. Keep kicking ass if you stay in development and I hope to play more of your stuff if you make more.
