The world contains 5 main rooms with pre-built modules that utilize different mechanics from the game. 

Room 1: Persistently powered automation.  Basically a place to test automation items in their most basic form.  Nothing really special here, but added for sake of convenience. 
Room 2: Automation with clocks. Covers basic clocks for drills, robot arms and item collectors. Also covers group item filters, automatic locked chest opener, item individualizers, and the snail clock
Room 3: Critter catchers and fishing nets 
Room 4: Enemies. This room features clocks and automation that utilize enemy behaviors, this features big larva, acid larva and mimite, 
Room 5: Complex automation. This features a modified MIF 5.0 (https://www.youtube.com/watch?v=HCNOYosnoTk),  a random meal cooker, crop clock, item counters, item clocks, automated crop farm BAMF (https://www.youtube.com/watch?v=70KwKdQn_E4), and mold tentacle machine gun.
