I've never had big hopes for the project but I feel incredibly happy that you like it!
The original I played on my friend's phone was just that -- a phone game, so making sure it works on my phone was a priority :)
I don't have an Android but last time I tested it was playable even though the cubes were bigger than I'd like them to be on some screens.
I've made an offline version for myself in the past to play while traveling by train. Copying the contents of the .js and .css file into the HTML file into <script> and <style> tags was enough. I wonder if I can make it easier for other people like you by storing it somewhere on git...
P.S. Here's the source if you want to create an offline-first version yourself: https://github.com/Kiryhas/memechain
