Hi there!

I have created a train, this is my first train ever. I wanted to share it with you, but suddenly the cats came and said that they will guard it!
But maybe you will be able to pass them? :)

Hints are available on the first page

The solution.

It's a binary cipher, where a cat picture means "1", and a non-cat picture means "0":

01110101
00111000
01000100
01110100
01000101

How you were supposed to guess it?

1. The picture array has 5 rows with 8 columns each. So binary would be your first thing to check.
2. I'm talking about cats, and it's a hint of what really matters here.

Two more secret giveaways were hidden inside the train: each 5th wagon contained a picture of my cat, if you hover it with your mouse, you would see a binary cipher for one letter/number. Collect them all and you'll get a bonus GA-code.

Thanks for participating :)
