I really like this concept, the cover art, and the warehouse environment as well, I think it could turn into a full game if you built on it more. If you do decide to keep working on it I would recommend give some of the workers agency so that if they see you move then they chase you. Also I think you forgot to make the worker navigation points invisible, unless those dots are for something else. The idea has a ton of potential and for a game jam the quality of the level is very good, I hope you work more on it!
