I love how the music changes depending on your situation! And the switching between characters idea is so cool for a stealth game - I really found the bird, salamander, and lizard really usefull. However, I didn't really understand the usefullness of knocking, or distracting robots with the Porcupine's quills. The art is really well done, and I especially love the effect when you switch between characters and the animation for the lizard's camoflague ability. It was a little annoying that you didn't get your health back when you went back to your last save, so I was stuck with 1 health after the first level, but it was a really cool idea, and really well executed too!
