This reminded me of the game Ghost Trick which has a fate altering possession mechanic and was one of my favorites. I liked the direction that you went for in having objects behave differently to trigger different reactions. The music is nice as well!
A bit of key control description would help and I think there were a lot of co-workers in the game all dying pretty simultaneously. If you were developing this alone, maybe reducing the employee count and polishing on the co-workers' AI would make the workload more manageable.
Overall, I think you should keep polishing up on this concept, I see a lot of potential in this.
