Yeah it won't work for me on Android at all. Even uninstalled what I had previously (so lost all my save games) and have tried both Full version and Compressed version.
Currently downloading on PC, so will see how that goes.
I was able to solve the problem for myself. I moved the saves to another folder on my phone, then uninstalled my version and downloaded the full version. After unpacking, I installed the game. The archive file is then copied to the Game folder. Then moved the saves from the replacement folder to Ripples. After the flawless start, the downloads and the unzipped files in the Download folder were deleted. In the end I had the files on my phone 3times. Download + unpacked in the download folder and finally under documents-renpy-saves...
