Fascinating little game that sets a troubling tone. I'm certain I'll be dreaming of those elusive circles and hearing that haunting music in my dreams.
Gameplay was simple, but the variations in pets was really intriguing and tempted me into finding them all. The actual pets were (aside from the adorable fox) disconcerting in all the right ways. Seeing the rigged creatures was really awesome too. I'd suggest maybe some cool outlines for the evolution guide instead of the actual pictures to entice more people to completionist status. I'd love a little acknowledgment of finding all the pets.
I did enjoy playing, but finding the toughest pet was a trial of patience as triple triangles thwarted me again and again. Still, after about 20 tries I got it and was quite pleased.
