I feel like I could use this game as an example of how a classic ANYTHING (movie, book, sport, song) can be successfully revamped. I don't think I have any complaints about this game. My knee-jerk reaction to not being able to push pieces immediately turned into looking at that as simply a challenge not a flaw. Upgrades are an excellent touch, too. This was a success all around and I hope it remains a top game here for a long time. Congrats!
