Looks like the link for the Android version got nuked. I didn't do the port myself (hence why it's labeled unofficial), but I will ask the user who did it for another link.
Edit: Added new Android link, thanks to Gamecax.
I reached out but there is no time frame when the Android version of 0.25 will be back up. Version 0.3 releases on the 31st, TBH I recommend you wait until that version is out. In the future, I am going to try to work on getting an Android version to release the same day of the main release and host it directly here on itch.io. I would port it myself but I don't have a Android device to test it on.
