Enjoyed using the new character controller, The little guy feels more fun to use. The new throwing animation also complements this new fun and faster feeling the game has. On PC, I personally preferred changing the magnet's polarity using the RMB button as it felt weird to control both the character and the magnet using keys very close to each other. After a level is complete, you get spawned to the very beginning of the hub world. I feel that as the game gets bigger, it will be a very long distance to travel in order to get to the next level, it would be better to spawn outside the entrance of the level you just won.
When it comes to the levels, I like the newer rapid approach to solving puzzles as the 1.0 version felt quite sluggish. You would spend most of your time moving to get into position rather than testing multiple strategies. The difficulty was not easy but also not hard, it was right inbetween.
