Hi there! I'm Jack. I wrote this article and created Gun Rocket. I can add more on my particular point.

When Gun Rocket launched, it did ok (maybe $100s). It made me feel great, but nothing life-changing. Most of the money I made was selling the distribution rights to a publisher (low $1000s). Again made me feel good but nothing crazy. They made some changes like a splash screen ad that I did not like. When that contract term was up I focused on removing that garbage. Idk when the explosion bug was introduced, but the point is I was surprised and immensely frustrated when I found it because the history of this game left my care and came back.

I agree that this bug existing for a long time reflects terribly on me. I hope that fixing it late is better than never fixing it.
