The Janitor (7DRL 2019)

Welcome janitor... We suffered a massive xenomorph invasion... Many employees have been killed... You have been hired to clean that mess! Be carefull, there are maybe some alien hidden on site. You have to clean all the blood before the teleporter activates to the next level. It looks like they managed to destroy and push some walls changing the infrastructure of the buildings. If some blood stains cant be cleaned because of this, you can press R to be teleported to another similar location. Use the arrow keys to move.
