This speedrun utilises the mechanics of We Can Change Anything, Portrait From Another World and Shelter From The 27th of March. Since an employee that sits in the shelter is immortal, we can use portrait to redirect the damage from WCCA and get almost infinite energy. Unfortunately, there is a save system, and employee in WCCA starts taking damage and dies eventually. So we need to improve the red defences of the employee in WCCA to get the most amount of energy in a short amount of time.

This technique greatly reduces time for boring and mental energy consuming grinding section of the game, making speedrunning this game way more enjoyable. This run was my 5th attempt, and I already got the WR for NG+, even considering that I got unlucky with the shelter dropping on the central department. I had runs where I got all three tools in the first three departments.

It is possible to do the run in sub two hours. I can beat this record, but I did this run as a proof of concept and I hope this will spark a speedrunning community for this game. Perhaps there was a version of the game where the WCCA didn't have a save system, and that would make speedrunning even more efficient.

The glitch was found with the help of LambdadeltaYT playthrough series.
