I wish there was just a little more time between when you click a shark (and it reveals the location of the frog and the lizards) and the transition to the next stage. It's frustrating because I know that it's revealing important information to me, but I can't see it long enough to recognize the pattern, or to remember it with enough specificity that I can work out the pattern later. Buuuut that might just be part of the challenge of the game, so ¯\_(ツ)_/¯
It is super cute tho!
