I've come up against a difficult (not impossible) level that I failed 5 or 6x. Each time I was offered only 5 extra moves for 10 gold instead of it progressing to 15, 25, etc. I think it was on my 6th try that I was offered something like 55 extra moves. Honestly, I'm not playing that much any more only when really bored so if I pass or fail it really doesn't matter. Still have plenty of gold and boosters left from All Stars but don't care enough to use them to pass levels. I just found this to be another "icky" twist to the game that confirms my decision to move away from playing as much as I used to. Wonder if anyone else has seen this.
