Hey cool game! I really like the idea of giving people quests. The even better touch is that you have to sneak into the back room to "respawn" the pigs, so really you are creating the quest problem in the first place!! Also funny having us walk around on the rug just like an npc. I ended with 36500 points.
I think some basic audio would make this game feel a bit more lively. It did feel a little solitary.
Overall though pretty cool! Good work on this!
