Itch has the "full" (still work in progress) version for Android. I got it before it was paid, but buying it here should have the same result for people finding it now.
For me it's just downloading the only apk I see up for download here, does it even have a demo?
That's actually act 4 already, 5 isn't released yet
1 is leaving the city, 2 is getting a lair, 3 is fighting the huntress/maelvys, 4 is conquering (and saving the princess) in case you're curious which act you didn't recognize as being separate from another
