Right know, they guys are experimenting with a new co-op mode!

What do you think it's going to be like?
I think that it will work like soulmates in Transformice, both players have a combined score and play the same pattern, but accuracy, health, and combo are independent.

Two teams that compete to get the highest combined score, or the dancers are in pairs. Both won't work if the number of cats in the room is odd though..

Would be nice if those of us with one could be paired up with our actual "soulmates" (not sure if they changed that in tfm, but being with some random guy absolutely sucked)

I think it'll give your soulmate and if you dont have one or they aren't online, then it gives you a random person.

Maybe they can make it average scores instead of combined scores.

This seems cool. Maybe in teams insted of pairs? I don't know lol.
EDIT: TAG4 mode? (Too much osu I've been playing)
Spectator mode so that you can actually see the notes when your dead/just enter room since it's boring when you can only look at cats dancing

I'm looking forward to this, specially because this mode suits the best to this type of games.
They could just use both ideas, one where you compete with other soulmates and the other with randoms patners
