This game is incredibly laggy. Why do you not include an option for the players to reduce the game quality?
Due to the lag, I'm not sure if the Flanders satan level is possible or not. Also, in that level, if you lose, you're probably clicking right at the exact spot where it'll then pop up a ton of windows to the flanderskiller website, since your cursor will be likely hovering exactly there (since that's where the Flanders satan's head is)
Probably should have thought that through better, so the player wouldn't accidentally spam-click your website just through normal playing of the game.
Should really do something about all that lag and also should think about placing the link to the site only on the title screen or something, so as people won't accidentally spam click it.
