There wasn't really a description, so I couldn't really tell if there was more I was meant to be doing besides just kinda walking from one end of the  level to the other, but based on the name and prompt I was definitely expecting some detective element to the gameplay loop; wasn't sure where the bunker part came in either. Also I climbed down a ladder and fell into an infinite abyss and had to refresh the page. Always nice to hear the Mushroom Hill theme though!
