Androidではダウンロードできないバグがある
Sadly, I do not have any control over network or download-related issues since Itch.io is the one hosting the files for download. I will say however that players who use a VPN to download the game from itch.io tend to have issues. Try changing your VPN location if applicable, or try downloading the game directly from the Public Game Post I made on FanBox or SubscribeStar.
