The movement in the V2.0 version of the game feels super good and is super fun to move around, even though you can only jump and change the magnet polarization. The only thing that I didn't like about the controllers is that when you aim to throw the magnet, you can't move around to perfecty aim the way you want, and having to keep pressing the same button to throwing feels odd to me, but maybe is my case because I don't usually play puzzle games. I would put the aim button just one button, the R1 for the PS controllers or the RB for the Xbox controllers.
Some jumps can be a bit tight for a puzzle game, if it were a platform game, it would be fine.
Ending the level just at getting the key, feels odd when you have to enter a room where the key is and it exits the moment you get the key and I feel like this game can benefit from the idea of getting the magnet to get out of the level, but that's up to the developer.
For now is fun overall
