I loved the intro! The physics puzzles are great, once I'd got a solution to the current puzzle I always found myself eagerly looking forward to seeing what mean trick you we're going to pull on the player next :)
Personal highlights for me were the second stage, just for the surprise, and ball pit which was just so cruel in the best way
Visual style is really clean and full of personality, and the choice of music is spot on to match it!
Really enjoyed this :)
