Yup, all things you noted are already in my to-do list!
I have to rethink sprint and add tasks that require you not to sprint or just remove sprint and make the character faster overall. Some sounds need to be completely redone (like watering and feeding, which are probably the loud ones you're talking about). The deers won't grow and won't make baby deers if you don't feed them - I'm planning on making a short tutorial explaining it. And I'll cut the time to 3 minutes which will keep you running and you won't get bored (which happens at about 4 minute mark from observing my friends :D )
Thanks a lot for playing and for the feedback! :)
