A few hours in and its already easily one of the best co-op experiences my partner and I have ever had. This includes previous titles the publisher has made which we also enjoyed, but this new game blows them out of the water. The humour and gameplay compliment one another fantastically.
Never have I felt areas were too repetitive, which is rare/unheard of for a platform game. This is achieved through each new chapter introducing it's own gameplay mechanics assigning both players their own specific roles which require teamwork and communication to coordinate together to achieve success. It has great replay value too in this sense, as replaying as the opposite character will give a new experience with different gameplay mechanics.
It's a really clever new IP and I recommend this to anyone looking for a fresh and fun co-op experience. It's honestly raised the bar for co-op and platform puzzle solving games for me and I hope other developers look to this game as an example of how to excute this style of game well.
