I played the web version until it suddenly stopped working, though I certainly played enough to get a sense of this game. A little absurd but certainly not uncanny, though it's a tight and fun challenge anyways. With a mouse, this never broke 'difficult' even on higher levels, but there's something satisfying about blasting the goofy ahhhh absurd animals with progressively bigger explosions.
Putting the difficulty scaling a bit higher so the game ends before things get too repetitive might add to the experience.
