Very smooth play, nice character movement and enjoyable shooting. I just played as the dog with the gun briefly and will have to come back to try it some more. I like the multiplayer aspect and appreciate all the work you put into it. I checked out the GitHub but found it was empty. I was curious to see how you implemented the multiplayer aspect. I too did a multiplayer game, using Web Sockets/Socket.io. Well done, if you publish the Source, I'd like to take a look and see what I can learn from it.
