Sound work is perfect. The audio in this game really shows the phrase "less is more."
I wish there was more info about the different red and blue wire's mechanics, but it still felt fun kind of learning through trial-and-error.
I really hope you continue to expand on this concept- its a fun puzzle system.

Nice puzzles, the only suggestion is making dragging requirements less precise, it's sometimes not comfortable with touchscreen to land the small dot directly on the top of the battery. Placing it just on the battery itself would be more comfortable

Well, that's a pretty decent and refreshing game! Clever gameplay. I felt that it needs something extra to keep me playing, but still, good job.
