Heyo! I've been playing Dancer for quite a while now and I just had to say, it's great. The flow of the rotation is really nice and the number of buttons is just right for me.
I think Tillana and Fan Dance IV are a bit out of place, given you can only use them once per burst rotation and they just seem to be there for the sake of more buttons, but honestly it's a very minor thing. The Technical Step rotation flows really nicely and I enjoy it a lot. I do however hope that there won't be new buttons added just for the sake of new buttons like these two.
That's all, I just like Dancer. Thank you for reading~ <3
