Visually, it’s very good, especially the parallax effect on the character’s shadow. Mechanically, it’s interesting, but I would be careful with the position of the ghosts in areas where the player doesn’t have 100% visibility, like in level 2-2, where I died as soon as I fell from the platform straight onto the ghost’s head.
The camera moving down when crouching is a good addition, but given how the levels are designed, it would make more sense to be able to look up as well. Regarding the cables, I think they could use a bit more highlight, maybe 1px of the lightest color in your game as a rim light, because I felt that the main logic is the construction of the cable paths and not necessarily finding them on the map. Along with this, I believe a more advanced puzzle construction in the connection between the cables would be more interesting, such as being required to pass through fuses or not being able to cross cables to avoid short circuits, all of this combined with what you already did to turn on the lights so the ghosts don’t hurt you.
But for sure, the game is well-rounded and enjoyable to play. I think that by tweaking those little things I mentioned, it would be a game I would definitely play to the end. Congratulations.
