It's a very fun idea. I like the plot and stopping the "peasants" from stealing your cookies.
few things:
- the music doesn't loop very well
- you are not really incentiviesed to move from the middle camera with the cookie jar
- it could be a bit more punishing (for example when you shoot the wrong guy)
Still it seems to be you first game, and you did it solo, I think you did a really good job overall. : >
