Top-notch puzzle game—this is one of my favorites so far! I found the puzzles to be both accessible and challenging at the right times (that last puzzle!) and the art style is really clean and readable—I really enjoyed my run here! It did feel like I had some trouble at a few points with dragging and dropping the batteries, but it always seemed to reset itself or get back into a state where I could eventually drag them again without resetting the level. Really nice work here!
