Sounds like some good all-round improvements. Were the changes based on feedback from those who played the game or just part of a general effort to improve the game?
I was not completely happy with the game. I thought that it was missing some things. So, I made the improvements and also made the ending better. Now, for less than a drink at Starbucks, any person can get the full 30 level version. I really thought that it needed more polish and variety.
