Building a relaxation app using a game engine (Godot). Good idea?

Hi everyone! 👋

I’m a solo developer preparing to launch the Open Beta of my Android app, Astra, tomorrow. Instead of a standard, static UI for a focus/sleep app, I wanted it to feel alive. So, I used the Godot Engine to build interactive planetary orbits where users explore custom ambient soundscapes.

Has anyone else here used a game engine to build non-game utility apps? What are the biggest pros and cons you've faced? I’d love to hear your thoughts and invite you to try Astra’s early beta!
