I like it :)
The game overall was all right, as well as rather easy. The images of the animals, as blurred as they are, can still be made out fairly easily. Perhaps to add difficulty you could make it a zoomed in picture instead of pixelated one. It would be tougher than just blurred silhouettes that can be easily read by people that look at animals enough to know them.
Perhaps other game modes would be good too...perhaps one without a timer or a faster timer...or maybe a survival mode that gives you only a certain number of mistakes through the whole game. Just some ideas.
I liked this game as I said before, and I wouldn't mind seeing an updated version in the furture.
