Hello, i'm Ascoth. First, I want to tell you that i love your mod (and you ^^) and I think it must be sooo hard to code (i tried to code in java, but i was quickly lost). All that to say that some stands like Echoes or Hierophant Green (which in the manga are high range stands) are just standing there next to his owner. You could make theme controlable like Aerosmith. Even some other stand with mid range like The World (10 meters range) or White Snake could be controlable to a lesser extent. Furthermore, switching Act with Echoes and White Snake could be more usable, because i noticed when you unlocked an Act, you don't use the previous Act because it's weaker. If it had a greater range, previous Acts would be more useful.
I don't wanna be the man who's like "work more, it's not enough", because this mod is already awesome. I just want to advise you.
Thank you a lot if you read my message, have a great day and see ya maybe.
(btw i'm french so sorry if i made some mistakes)
