What is URP? In comments someone says that non-URP version works fine, so I'm curious if I've lost any content or gameplay mechanics in NoURP apk?
No, there are only visual bugs that you can see in the rebuilding diary in comments
In non URP, there will not be any special visuals in night stages like level 3.
If you happen to play it in URP version stage 3 will look like this once you enter the cave.
