jokes have meaning and your life doesn't

PLEASE DOWNLOAD THE GAME FOR THE BEST EXPERIENCE!
CONTROLS:
WASD to move.
Mouse to aim.
Left click to shoot.

OBJECTIVE:
Shoot jokes at people to make them happy. (If they haven't exploded, they are not happy enough)
Avoid other's projectiles.

BACKSTORY:
Backstory is irrelevant. Your life has no meaning anyways; why should i even tell you? Nothing matters anymore, just shoot guys and gals with jokes to make them laugh.
There is definitely not a secret reward in level 6 so don't bother looking for it. Just don't. Its so meaningless.
