I've noticed that the scoring is jacked up on a couple of the arcade games. I'm guessing this isn't something anyone here can do anything about, since there are probably problems with the way the games are coded, but if this is the place to vent 'annoyances,' there's one.
In Add Like Mad, if you don't submit a score and simply start a new game, you get a cumulative score from all games you've played until you submit.
But the really annoying scoring bug is in Rotation. After hours of trying to beat Level 8, I finally did, and the game ended, froze up and wouldn't update and/or let me submit a score. grrr.... If I have time, I'll try it again tomorrow and see if it behaves.
Really not a big deal, but I was so excited to finally finish that damned game that I'm rather disappointed at the moment and needed to vent.
