JUICE: Using the pliers is very satisfying. The sound is good, the screenshake is nice, and the way the juice stains cover the floor is a great touch.
Gameplay: I like how you included humans as interference, and that they gradually increased. Well balanced.
Graphics: Love the little fruit people, and I appreciate that you included two different types. That really adds visual interest. At first, I thought the humans were monkeys, so it was a bit disappointing when I learned that they weren't ;P
Sound Design: Good music, and good squelching sound. Something to suggest the time limit would have been nice. Like a countdown "beep-beep-beep".
Respect of the Themes: I guess the pliers are mirrored? Seems a bit of a stretch. The second theme is definitely there, with the time limit.
