I built a tiny logic game in plain JavaScript — no frameworks, no accounts, no tracking. Just logic.
Then I turned it into a Progressive Web App with two files and ~50 lines of code, skipping the app stores entirely.
Why?
No ads, no data collection, no fees — just a puzzle that works offline.

If you’re building for the web and wondering whether “native” is really necessary — maybe it isn’t.
