It'd be great to get any feedback on these. I've tested only on a Samsung 4S-mini. Some notes:
- Inside, the apps are Cordova and ~1500 lines of vanilla ES5 and CSS
- Behind that are some build/preprocess steps which basically flow: img scraping and resize scripts -> [content] + ~100 line yaml config -> build scripts -> apk
- Prototype app includes diagnostic controls for the game/passtime itself and various DOM event/property logging used to construct/refine things
- The "finished" apps are intended as a boring-as-possible, feature-minimum case
- Thinking about whether it's worth developing this or similar toward 99¢ apps, custom versions, an SaaS approach or something else
