Thanks for the feedback!
Ya this playtest has shown it might have needed a little bit more content to really see if the partner mechanic is something special. I guess I was worried just the act of controlling two characters in a action game might be too much, but most people said they wanted more to do with partner. I guess that's enough incentive to flesh it out a little more.
You mentioned using the partner like a fighting game, there was a point were I wanted to make it like that. Essentially a 2d DMC game with assists like a fighting game. Hi fi rush does this a little but I was wanting more with the assists, possibly even with quick switch/tag like 2xko/MVCI. I still might fall back to that if this formation/command based one isn't working out. I'm going to test out this way a little longer at least.
Thanks for playing!
