Cargo Cat - 2D side scrolling

A classic 2D pixel art side scrolling platformer game.

Story: You are a cat on a cargo bike and your job is to handle packages. The packages and delivery locations are on platforms on the side of buildings in this 2D side scrolling game.

Borrowing a convention from many other side scrolling platformer games, some platforms have boxes with a question mark. Those are special items: some so good they can enable you to quickly win a level, but some are not so good...

There are 20 levels, getting more and more difficult as you progress. Can you go all the way up to level 20 in this 2D side scrolling game? Very few people have managed past level 15...

The game has been tested with children aged 8+, the reading required is appropriate for them.
