LOVED the game. I did encounter a very small bug though:
When you go outside, I believe your brothers are randomly placed? When I went outside for the second time, one of my brothers was standing right outside and I pressed space to talk to him immediately. When the dialogue finished, I couldn't move. Pressing the arrow keys just made my character look in a direction, but he didn't walk. Space bar still opened up dialogue with my brother.
So I restarted the game but got to where I was quite quickly so it wasn't that big of a problem.
