Shifter I really like the concept of this game! Never saw a puzzle game with this concept, really neat! I love the art style and the color palette, these tiles are gorgeous! Really nice map transitions!
By the music i can tell that you want people to kinda chill thinking about how to solve the puzzle, but anyway maybe the player movement could be a little bit faster (i would make the speed of the 'chunks' a little bit faster too), i think this will not change the mood of the game!
I found a bug, if you move the player when restart a map (in the transition), the player disappears!
Great job, keep making games!
