I'm glad you enjoyed the music! This track was originally planned for a NES game, using Famitracker.
Regarding the game being in a playable state, I would say that it is kind of in a playable state, but definitely not a good one, or a really enjoyable one. It is possible to finish the level with a combination of card scrapping, searching and moving.
I have updated the game's page with a bit of info on how to play the game.
