Cute little game! Certainly a unique take on "Electric". The pixelart is quite pretty, and idle animations are a nice touch too, giving off the feeling the art dances to the music. The soundtrack sounds pretty good.
I couldn't read the tutorial, it autoskips way too fast, wish it would've waited for player input - you already have the "there is more text" hint at the bottom.
The neuron graphics are also cute, but they feel out of place since they don't have the same pixelated style to them, and appear to be blurred/deformed from stretching. It was quite hard to understand what shapes some of the neurons were supposed to be (e.g. the big one in the 1st level, and the 3-tile neuron in the 2nd level).
