I really wanted to play this game and purchased the Beta demo but I'm also having the jumping issue and walking sound, tried everything to cross the fence but can't and it's frustrating. It's unlikely I can be able to get a new machine any time soon to play this properly, which is sad :( I would also just like to ask for a refund, and wait until the official fixed and finished version is released and a proper machine to play it on. I still love the concept. Thanks.
