Can you give me a hint for stage six? That's the one with two beetles, two mantises, cat, tiger, pangolin. I can't find a solution or, more importantly, work out why some of the ones I'm trying aren't valid solutions.
Thanks, got there in the end. I feel like the game could do with more feedback (maybe something like a tick or cross on each set when you submit) but I'm not sure if that would make it too easy.
