There should be a train car with some random furniture thrown around and 3 buckets of paint and you have to design an aesthetically pleasing room and if you succeed you can continue on your path to kill the train Conductor but if the room is ugly, the train car fills up with slugs that speak French and wear tiny barets
Here are the 3 paint colors you get
Some of the furniture peices you get
This is the TV and stand
This is the only piece of wall art available
You are allowed to paint murals and the furniture, you can choose whatever you want to put on the shelves and have access to an infinite library
Here is my rough design
Make your own with the blank train car under the cut
