I really enjoy Just Dance; but this version not so much.
1: There is not an option for left hand playing (not just for left handed people - what about people who actually only have one hand)
2: When you reach a top score on other versions it has saved the player's name as their top score, whereas in this version it just says what the top score was and not who won it. I'm assuming because of sensitive people who don't like losing haha
3: Next downfall is it is quite expensive for the amount of songs you actually receive. You have to pay extra (not even a one off payment but actually per year) for unlimited songs.
4: If you play the game with one Switch Profile the progress cannot be shared on the console with other profiles. Even if you make multiple "Dance Cards" to see each family member's progress it doesn't work as they all have the same top level dance score, so it's boring.
I'll try to explain. I myself am okay at the game 9/10 times I'm the highest scorer when we dance together, but all the dance cards aka family members are the same score. Terrible score keeping for families who like to have a bit of healthy competition.
Overall fun game, but definitely not worth the money I paid - even on sale.
