Cool use of GB Studio, if I had a flash cart I'd give it a spin on my actual GB. The puzzles worked well, but it would be nice to subtly visualize the flow of electricity on the actual wires a bit. I would've liked to see some more complex puzzles at the end that combine multiple pieces from the previous ones. Most of the puzzles had such a small possibility space that it was trivial enough to reach the solution by just trying every option available to you, which doesn't make for a super rewarding puzzle. The visuals are very clean though, and there are some great ideas here. I particularly enjoy the sokoban-esque batteries. The limitation on how far you can push them from their charging spot could make for some compelling challenges.
