Great game !!!
The gameplay is simple and the difficulty is well balanced (especially in the final levels, where you have to use your brain instead of just running into the crowd). The recurring music is catchy and the animations of the little characters are adorable. The controls are good, and I recommend playing with a controller (which I did) using any gamepad input mapper.
The game may be short (10 levels), but it's a lot of fun, and there's something very satisfying about turning crowds into zombies.
