This is neat and novel. There's only 2 things I would like to be added or changed:
Consistent pixel sizes and alignments. This is likely due to you leaning on android UI API despite the retro look.
Ditch the Android UI stuff. I am actually undertaking a similar project but with C/C++ and Raylib so it can be cross platform, even for the web. (Doing this can allow things like Lua as a scripting language for the end users to use ;))
