Totally doable on mobile. Perhaps you can set Firefox to always allow zoom in a11y settings. Zoom helped me a lot.

I got stuck on finding a "guitar cat" in Germany.

The guitar cat is on the back of a guy's t-shirt, he's on the opposite side of the square to the stage and facing away from it.

Thanks.

Now I'm stuck on express yourself.

Maybe I'm a robot after all.

EDIT: 5 or more colours does the trick

I still can't find it him! More help would be very appreciated

You can "restart" that challenge (with the bottom left "arrows in a circle" button) to look for a couple kissing or a chilli's sign.

I found the latter (it's SPOILER in a window)

		The couple kissing SPOILER ALERT is towards the top right area of the image, in the middle of the street standing up
