I really liked the way you used the Kenney assets and created basically a helicopter attack game. I thought the scope/crosshairs view was really cool and made me want to shoot up lotsa zombies. I have to say the controls were pretty janky, though--especially firing the gun, which seemed to happen only part of the time I pressed the mouse button and I wasn't sure why. Could also have used a few instructions on how to play at the beginning, as it took me a while to figure out the keys.
