Hell Is That Noise: The Glitch's laughter whenever it uses its rapid-fire attack. Made worse as the fight goes on, as the lower his health gets, the faster he throws this attack out and thus he laughs almost endlessly until finished off.
Nightmare Fuel: The scene of Garfield getting eaten by a TV whenever he runs out of life followed by evil laughing. Not helped that this acts as a continue screen (literally putting Garfield's fate in your hands as he watches nervously if you will or not) and the Game Over screen.
So Okay, It's Average: Most of the panning the game got from critics is that aside from the series author's personal touch, Caught in the Act didn't bring anything new or imaginative to the table as far as old platformers go.
