URM can be use in almost every renpy game, but there are 3dg/animation that flash a new layer of image which make the URM icon disappear. To solve it, you only need to go to URM setting and turn on the icon bar or just simply save and load in every new scene/layer that will make the URM icon reappear (probably looking for path/route). Those are the easy way to use URM because changing rpa file to fix something unnecessary stuff is a pain and mostly get more error rather than success.
Yes, but I'm looking for the source problem that causing the gallery won't play the replay and I found out why, it's simply because a wrong value in the script line <Yoga_dream> which supposedly <Yoga_dream_1> on the raw game it's easy to fix but for android port, well let it be since URM could do the job anyway. have a good day and enjoy.
