Unpacked, the 1.5.9 update doesn’t just fix collision detection on a staircase in “Mansion.” It’s an apology and a promise. The changelog (buried in a release_notes.txt few will read) speaks of “refined joint constraints” and “optimized object pooling.” In human language: your wobbly avatar will now grab ledges with slightly less existential despair, and the game will crash less often when you stack fourteen paint cans on a seesaw.
Ensure you have at least 1.1 GB of free space, as the game's file size has grown significantly with these added levels. Human Fall Flat Update -NSP--Update 1.5.9-.rar
