This game was amazing, I liked the simple gameplay and art style, but I felt a lack of more substantial controls like selecting multiple pieces to move them all at the same time.
Also, the game was way too easy, there was always a high amount of pieces which you didn't need, that made solving puzzles not require much creativity, just putting the pieces in the right order, it would've been nice if there were more levels like the bonus level, where you need to combine certain pieces in a different way, and levels where you need to use all the connections in the pieces.
