So I fixed it. Deleting the game from the hard drive and redownloading it, somehow, fixed all the control issues. No, I don’t know how.
Now, I can draw whatever Unite form I want and it works every time. And it’s a good job too, because it turns out when it works properly, the game is awesome.
I’m able to dodge or block attacks now. I don’t have to spend half my play time fighting the controls. I’m really enjoying it. Phew, eh?
It does make me wonder, though – did the reviewers get the same broken version I did?
Anyway. Progress: I have defeated the giant that tries to smash you on the top of a tower, then you go inside him and smash his… Brain? Dunno. Awesome.
