Android User here and, honestly, I'm quite impressed! No issues,crashes, etc., with Android Demo and the art is gorgeous (Now, I wanna replay Endless Bounty~ ♡).
Only thing I can suggest is... Although not sure how feasible... But a way to hide the D-Pad / Buttons would be nice as they overlap with the villagers at time and just... Just kind of in the way at and inconvenient (since they're not very transparent); Also, smaller buttons would be nice, while the size of the D-Pad is fine, just too intrusive...
Finally, while I had no issues with the scenes when they occurred playing the game (That barn scene~ ♡♡♡), I wasn't able to replay the scenes in the Extras menu, but wasn't sure if that was just an intentional limitation of the demo. However, the cast bios worked fine :)
Nevertheless, keep up the good work and I'm excited to play the full version when it is released~! ;)
