I ran into a bug on the 3rd or 4th level. The "You correct flagged 100% of the transaction." message was stuck at the top of the screen and I couldn't see the first 2 ledger entries. Nothing seemed to get rid of it.
Doh, I apparently displayed both the "You win" message along side the "You beat this level" after level 3 and only got rid of one of them. Sorry about that, I'll fix it and push an update. There are only three levels at the moment, so you won the game it just bugged out at displaying it.
