I started playing this game 2 days ago, and it's very good.
One thing that annoyed me was that before playing against occult, I had unlocked all of the possible characters, then I lost against Occult (didn't have time to do the Dragon Tornado, I thought the Dragon shot would do it...) and I hadn't saved the game... (FUCK YOU GAME FOR NOT HAVING A CONTINUE OPTION AND FUCK ME FOR BEING SUCH AN IDIOT)... I started at the beginning of chapter 2. Almost raged-quit the game...
Now I'm at chapter 4 and I'm worried that I'm going to run out of character space, I guess I'll end up kicking most goal keepers out of the team, but it's kind of disappointing that there is limited space, the completionist inside of me is not happy about this =P.
Good game overall, but definitely needed more polish, it's beautiful, but the collision detection while running on the map is horrible, invisible walls everywhere.
While playing matches, the referees suck a lot, having only 5 replacements is fucking ridiculous (should have been 12 or 17, like real football), the matches are too short IMO, the tactics are too limited, etc.
I would rather have less characters, but put a lot more focus on them. I guess I'll begin putting only characters with a key on them, overpowering them and forget that the others exist =P.
