Hey! I updated the android version recently to fix the v.0.3 ending bug so it should work properly now! About the download fail, can you describe the issue more to me? It might be caused because of the lack of space on your device.
Thank you for letting me know. The Android version has been reupload and I added an external MEGA download link for the android version, please let me know if you encounter any other issues. Sorry for this inconvenience, have fun playing! 😊
