Thanks for playing and feedbacks.
The first issue was acutally a controller input error. About the second issue, I tested it several times and even tried disconnecting and then reconnecting internet mid-game but the highscore worked just fine to me. So unfortunately I can't handle this issue.
I have released 1.4.0 patch to fix other issues and add some tweaks. Can you download 1.4.0 version and see if the highscore feature still doesn't work after some minutes ?
