Very nice game! Great concept, cute design, solid puzzles and sense of progression/difficulty, all in all this feels very well put-together in all aspects and I found myself getting addicted to making my way through.
Having said that, I did have a lot of issues with it. First, the game was a little wonky in some aspects. In terms of the controls I found myself initially wishing that I could click to pick up something and click to put it down, instead of holding and letting go. Not major and I got over that rather quickly, but speaking of plugs, interacting on a plug and seeing no reaction until you walk away to rip it out from it was a bit odd: I'd prefer if the plug got immediately ripped out when you interact. Plugs in general were wonky as well where I had plenty of times where I had difficulty keeping them plugged in: they'd pop out randomly for some reason, and this wasn't even a case where they were on a short tether or something like that.
Second, I found the game rather unclear on some of its aspects. I actually spent a long time thinking that my character charged up as long as I stood next to a light source, or more specifically a lightning bolt symbol: it was only until way later that I realized that I was recharging because I was standing on these charge-up floor things. I had no idea that was the case as the floor chargers seemed like they just blended into the environment: maybe make them pop more by coloring them differently or giving them some sort of effect. Secondly, I really wished that the direction and flow of power through circuits was a bit more obvious, in that I wish it would not only light up the lightning bolt at the end, but it'd be great if the whole wire would light up as well, maybe with a little flow animation for the power surging through: it'd be so much more intuitive to grasp and satisfying to see.
Third, I really don't agree with the design decision of having the main character run out of power when moving outside of charging areas. Yes, I get what you're going for and I think it works for some of the puzzles in the beginning, but once I got to the later puzzles which were very complex, I found myself dying constantly because I'd get so into solving the puzzle that I'd lose track of my power. It just felt like recharging myself was unnecessary, annoying busywork that got in the way of me having fun solving the puzzles: really ruined my flow. It was also annoying how some movements, like hanging from a cord and swinging drained energy even though I technically wasn't expending energy in a literal movement method, if that makes sense.
Now I know I just wrote a giant spiel of negative feedback, but still, I do like the game for the most part: I'm having fun and certainly plan on continuing the rest of the way through. Kudos on this!
