The concept of that frog's tongue is quite interesting, but I think there is some work to be done balancing it out, especially the speed of the tongue VS the speed/unpredictability of the fly-movements. For the moment it is quite hard to catch them when they are further away, and you kinda have to hope they come close or stay very still, so it ends up being too much chance and not enough skill for my taste.
Still, nice little game
