What a great execution!! It's similar to what we created but far, far more polished :) I wonder if a visual gauge to indicate the level of charge or how far the cat will go would be nice, although it is also part of the challenge to learn how the cat moves, and the eyes widening to indicate full charge is also helpful. I got stuck by putting the head and the tail on opposite sides of a small horizontal platform, but managed to get unstuck by mashing both buttons. Very nice work!
