Kongregate just supports the games, they don’t maintain them. The best thing to do is to file a bug report with the developer. To do this, go to the game page and click the “Report a bug” link found in the info box. Fill out the report accordingly and if you don’t hear from them by say, Wednesday then you can contact firstname.lastname@example.org. Since it’s a weekend, you probably won’t hear back from the developer until at least Monday. The same thing with Kongregate’s support channels, they only operate on business days.
[Edit: Unfortunately the process isn’t an instant fix, please try to have patience.]
