I did not love it like others, felt like the game had great ideas but I would not say they are fun ideas. Clever sure and the first time you change world because you pushed a lever and made the world flood indeed feels clever but then you see you missed a coin in the normal not flooded level so you have to go back to the overworld to switch the lever again...well that process isn't fun. Rayman Legends had those music rhytem levels and I thought they were clever, challenging and fun. Also the controls YK IL feel a bit weird, you get used to it tho.
I would give an 8/10 and a must for nostalgic fans (its dirt cheap now aswell).
