Where's my Balloon?

Where's my Balloon?
by K. A. Laherty 2015 (Browser version made in 2022)

"in the year xxxx2, A very pixelated monochrome individual lost his kitty.
After much shooting and jumping, he saved his kitty.
It seemed all was right in the galaxy.

But 2000 years later....
A green badly drawn pickle-biped purchased a balloon,
But then some unknown force stole his balloon.
Now the shooting and jumping must start all over again..."
