I agree :/ I'm glad there's a topic about this. Also Arcade mode does require an internet connection to use, else you wont be able to play and list a score. There is also a support/contact option in the forum (at least, I've tried Settings -> Support), although the response (via email) is non-english. I hope the developers or the company focus on this issue.
It also affects any spirited effort in trying. :( And this is a good game! I've never understood why certain few people want to cheat (in public or whatever).
Obviously, this is in direct violation of the terms of use (easily read, with a link at the bottom of the forum and in game).
