It's been a while since I have played Retrofab but I just got a newer Android phone (Samsung S20.. a few years old but "new" for me) and one of the first things I did was to revisit some of your sims. Quite a few new additions since last time I visited, many thanks.
Would it be possible at some point to include a feature/button for the game device to automatically match the height or width of the screen? You can zoom in and out with fingers on phone, but it is very touchy and quite hard to match the screen size exactly.
