I'm not sure what the deal is, but I've upgraded my laser completely, and then played the next level (11), and then it says my laser hasn't been fully upgraded, and is only sitting at level 10 instead of Max. Happened twice now.
There seems to be a built of trouble with the save feature. I understand that it saves after a round, but even after buying the max clips, playing around, quitting, and then coming back, it doesn't show the full clip :\
