I don't know why, but the game on android crashes every 10 minutes (at the beginning). Get real annoying fast. It became more pronounced the closer I got to completing all stories (left sarah and sister for last). At the end I had basically 1 scene per crash. I had to reload the game, load my save, play the scene. Then I could play for few minutes, but would always crash before next scene.
It is a great game though and that is the only reason I finished. Damn that sister ass groping animation is on point - really sexy.
