We're glad you enjoyed it, we both watched your playthrough. We noticed that it wasn't obvious that you can click the cat names to show some hint-text so we were impressed you found them all by just looking at the silhouettes!
Ah, yeah, I had no idea there were hints, that's cool though! Maybe in the tutorial it might help to mention it? But besides the bush cat, it was challenging enough but not too hard. =]
The tutorial actually does mention it as you have to click one of the cats and show its info-box to proceed but it seems that it wasn't clear enough :)
But I'm glad it was challenging enough still!
