There honestly needs to be more information or something, I have absolutely no idea what to do with the dog that chases the agent, I've looked around and can't find anything to deal with the dog, there's no interact option on it and I have no weapons as far as I can tell.
You need to have visual clues to help the player understand the developers ideas and motives. Remember that people are playing a lot of games in a game jam and most people will only repeat a game from the very beginning 4 or 5 times max before they move onto the next game.
I really like the graphics that you created, everything is clean, fits together well. I think the perspective of the sidewall starting area sidewalk is too long though compared to the rest of the level.
