This is a fun game but you have a broken medal, get to level 30 on classic mode.
Spent hours trying to get to level 30 in Caos mode. On a Friday evening. I finally achieved it... and didn't get the medal. I have no words to express my disappointment.
I'm sorry to hear that man. :( did the ingame popup showed? I coded the medal to appear after beating level 30 not upon reaching it.
I had double check the code before answering and everything is correctly setup, so my guess is the server got disconnected while you were playing. The current stage score for you that the server saved was level 23 so maybe that's when it happened.
Great game though you should probably change the feel of repetition, loved the 3 different boosts and the 1up every 20000 points and the classic saucer, Keep it up ;)
