After the update, playing the game is fun. The different types of platforms and dangers are a nice combination.
One thing I noticed is that if you fall from a greater height onto a magnet's to side, you still die.
Another thing I think would be good is the player automatically following the platforms when moving side to side.
If you want the extra movement space with the side walls, maybe make them so the character does not fully disappear but rather leave a small part of it visible.
Also, while the character movement generally feels nice, there is this game on itch.io explaining a lot about platformer controls, if you want to look at it: https://gmtk.itch.io/platformer-toolkit
