This is really good example!
My only observations that require improvement imo: 1. when running, the controls are not very responsive, I don't know if it's the browser game's fault, but when the character is running, sometimes it doesn't allow you to change direction 2. there is no backpack for items in the game, right? it's just a question, no objection 3. when it's dark in the evening/night, after changing the map the darkness is "loading" for a while 4. you can put chickens on walls.
Anyway: this is really so good!
