Get JoiPlay and the Ren'Py Plugin, put the windows version onto your phone and run it through JoiPlay. I had problems with running the Android version myself, the JoiPlay work around did good for me, maybe it will work for you.
As for a refund, i'm not trying to influence your decision, but I wouldent refund. This game is awesome and deserves the support. But in the end, your choice.
