I suppose I should have expected this, but the levels above 3200 just get to be almost too difficult to manage. 3207 and 3208 both took 15+ tries to succeed, despite a complete set of enhancements. 3231 took 14 extra moves to slog through, after multiple tries. I have stuck with it as a team leader, trying to get bonuses for the members of my team, but this is getting to be very little fun anymore. Perhaps you should consider spacing out the difficult levels a bit more. Even the unlabeled levels (not labeled "hard" or higher) are significantly more difficult than they were under 3200. A less abrupt transition to the challenge would make the game more interesting, in my opinion.
