Hello,
Due to its internal structure, Female Forge is currently impossible to port to mobile.
However, I am thinking about a lighter version (dedicated to small hardware configuration) and less RAM-hungry, because FF uses PNGs in 4k (ideal on 2160p screens) and it is indeed quite heavy, but the problem is that to make FF lighter, I will have to reduce the resolution of the PNGs and this will greatly affect the visual quality and will be usable in correct conditions only on a 1080p screens.
In any case, the "Lite" version is an interesting idea and thank you for your comment.
