My impression so far is based mainly on the co-op mode

Pros:
Co-op is fun and forces you to work with your partner
You're able to have funny interactions between characters
The characters have unique personalities and well written dialogue
Different elements are introduced along the way to enliven the puzzle-solving

Cons:
Too many loading screens between levels which takes up a lot of time
You play as robots in co-op
Can feel repetitive
