Thanks for your feedback.
I have already watched him making the magnet game, he was trying to make a balance between puzzles and platforming and discovered that they don't work well together so he took the puzzles side while having really simple platforming.
When it comes to puzzles in this game, they are pretty simple because the game focuses on platforming (and combat in the next update) and the puzzles are used to make the play think a little bit, and the machines are used to spice gameplay more.
