There is no download for android.
You can create shortcut of the official site https://htopia.online to your home screen.
Wouldn't i lose my saves too?
If you've been playing here on itch, you could download your save files, then upload them on the official site version.
To download them just go to the Save screen and click the download button on each save slot you want to backup.
Ohh i see, thanks!
