Solo Dev’s First Launch: Banano-Shot Journey, Could You share Your Insights?

Hello I’m 9MR, a solo developer from South Korea, crafting Banano-Shot (an AI image editor)during late nights while working a full-time job.
Launching it 2 weeks ago has been a wild ride, with many users engaging and great community interest.
I’ve learned a lot from small ad experiments and your advice.
What challenges did you face with your first launch, and how did you overcome them?
I’d love to hear your wisdom! For real.
