I can't do much here. I don't know how it will be when I port to Android, but since LA has a lot of animations... sometimes those things happen. I can't do more than what I've already done over the years (memory usage optimization). On my laptop, I have 16GB RAM, and if I move the mouse too fast, it lags (it happens with any Renpy game) so... Also, some versions work like ass and others like a charm; I don't know what mysteries are behind all that because I don't do anything different in each version. On my PC, everything works perfectly, and on my phone (Pixel a6), when I do tests too.
