please clear data on the android app if you set things too high causing a crash. Clearing data will reset your settings to default.
Depending on your device you may need to stay on low quality, alternatively lowering render scale can help, but it won't help with memory problems.
Part of the reason is the updated apartment scene as much more assets and textures than just the room. And increasing quality also increase texture memory limits.
I intend to optimize more, but it will take some time cause the optimization method makes the scene harder to change and for a game in mid development thats a problem. Other optimizations are planned too, but that stuff is still in development.
I would like to know what device you have though.
