Your device might be underpowered. Maybe the web edition available on GameJolt runs more smoothly?
So what are the minimum specs to play it?
I got 4 GB RAM with 64 GB ROM with Processer MediaTek Helio P22
It runs other games of Ren-Py smoothly though. Sisterly lust isn't the first game of its type I played on this device.
The compressed version should run on that hardware. During the backstory you have a couple of name inputs where a keyboard is shown, does it crash there?
Yup! That's the part. 70% times it crashed there and maybe once or twice afterwards
