Hi Mark, I loved the game - the graphics were splendid, the puzzles were challenging and the character felt great to control. I did have a few thoughts however:
-As other people have said: many of the puzzles feel quite cluttered and it is difficult to understand what is going on in a level before you actually try to interact with it. I have a couple of suggestions that could help:
-Colour code the wires - you could use the same accessibility settings as you did with changing the polarity colours for the wire colours as well
-Try to keep the puzzles on one screen that doesn't move, I found that I felt a little overwhelmed when the camera started to scroll
- Also, I'm not sure how well this would translate to your game but I found myself sometimes wanting a Baba Is You-like rewind as occasionally I would press the wrong button and have to restart the level because I threw the magnet somewhere where I couldn't get it or I accidentally messed something up. This is just something I thought might be handy.
-As for bugs, I didn't find any except in the "Thanks for Playing" screen, if you press and hold the restart level button then the restart icon just appears from the corner and slowly gets bigger the longer you press it and then disappears when you let go -- A clip is attached demonstrating this
-Lastly, (this is also to do with the restart level button ). I am hopeless when it comes to remembering what button does what in video games so I found myself randomly accidentally restarting the level, it might be nice to have to press and hold the restart button and this could be accompanied by a little animation on the restart button - maybe something similar to this : Reset Animation Idea
