Fun little game! I'm a fan of top-downs, so I was happy to play this one. I ran out of ammo for the last 15 or so, which made things intense. If I were to suggest one thing, with these exterminate-every-enemy type levels: When you get down to the last few, it really helps to have some indicator giving you the direction of the nearest remaining enemy. I think half of my play time was just wandering around, looking for those last five zombies.
