Cow Crossing and Cherry Blossoms are nonexistent for me. Is there any reason why they aren't there?I can't do full game runs, because skipping 2 levels would not be allowed I think.

It looks like you have an older version of the game. I own the newer version which contains the two levels you're missing, but I'm not sure if I'm allowed to send a link to the zip file here. If you see this just let me know :)
