The print-and-play version of Puzzle Strike now includes the rebalanced characters from the Puzzle Strike Upgrade Pack. This free update has actually been available for a while, I just never really announced it until now.
Anyone who bought the print-and-play (or who bought something that automatically included the print-and-play) can redownload the files with the same links you had before and it will now magically contain this update. I just re-sent those download codes to everyone, so you don't even have to dig through your inbox.
EDIT: Looks like that new e-mail you all got accidentally has the wrong patch notes. Sorry about that. The files themselves really do have the updated character chips.
If you set aside Puzzle Strike for other games and never went back, I really urge you to give it another try with these rebalanced characters. I hope you find a lot more interesting dynamics this time around.
As far as I know right now, the physical copies of the upgrade pack should ship to everyone the beginning of next week. I know it's been a long wait, so thanks for patience.
