I'm sorry you're having trouble! Can you give me more details on the situation? Is the file not downloading at all or is it failing to install or something else? Are there any errors being reported on your android device you can share? And, if you can, could you email us? We'd be able to better go through the troubleshooting process through email rather than the Itch.io comment area.
