Eagle-eyed streamers found a couple bugs in the stats screen. 

• The "Blocks Cleared (Total)" stat was being incremented by the wrong variable and the math obviously didn't add up. That should be fixed.
• The "Total Combos" stat was being incremented incorrectly and was a pretty arbitrary and overinflated number. Your save file will be updated, but as a result your "Total Combos" stat will be reset to 0. Sorry!
