I got 17,000 ish on the space invaders tounrey, and submitted the score, however it comes up saying i've played twice and got a score of 0. Its not just me, a few others are encountering this problem . Not sure wheter you can actually fix this, but im just having a moan.
I hear you loud and clear. Playing tournaments is a scary business. One wrong move and you're disqualified. In most cases the game will automatically send in the tournament score, so clicking submit does it twice. The best technique is to wait 10 seconds after the end of the game and if nothing's happened then press submit. Unfortunately there's nothing I can do about it. The guy who created it has almost finished his next version which "hopefully" will be less sensitive.
