I have been working on this project for past sometime (on a sabbatical). I have Android and iOS apps built with ReactJS/Cordova. It uses modified p4wn engine to accommodate a new piece - crab in stage 7 (moves zig-zag). Backend is in Nodejs (uses a DI framework known as archiejs
https://github.com/archiejs - that I wrote). Leaderboard uses heroiclabs API (heroiclabs.com). It is hosted on gcloud - app engine(1-5 insts), a mongodb db cluster (2 insts) and redis cache (1 inst). Everything is g1-small instance for now. I am using Tappx (tappx.com) and Admob add networks for monetization. I will be happy to answer and take feedbacks on technology, product, etc... Do ping me here.
* Rule to remember while playing - stalemate is not a draw.
(Also note, I can be approached for remote development work - nodejs, reactjs, fullstack - flipflopapp.com/files/NavalCV_short.pdf).
