Some F2P card battle/city building hybrid for iOS and Android by Nubee Tokyo. Four surprisingly lengthy tracks (19min looped once) by Sakuraba with nice melodies and plenty development. Not sure if there are further tracks at a later point but it doesn't look like it.

Not idea if the same as the above rip (5 tracks + 7 jingles, each track is ~2-3min).

To get the looping working, rename the .ogg to .logg and a play them with vgmstream (it's the only thing that supports looping ogg and wav AFAIK).
