I like the idea and the take on the theme. The art style is also nice.
I did find the game rather confusing to play though:
- Some hint as to where the locations I need to go would be appreciated
- I wondered around trying to find my office for quite a while
- The interactions with the employees didn't seem to work when I clicked on them
- I don't know if there where supposed to be only specific people I could "talk" to?
All in all, I didn't managed to get past killing a single employee (couldn't seem to interact with any more), but if there were some fixes I would look forward to playing and seeing the boss battle.
You've certainly done a lot in a short time!
