They've done this before. Yes, I contacted the developer., I read the reviews and everyone wants the old version back.
They changed the algorithm and it's not fun anymore. You used to get a set of dots where if you thought hard you could get a really high score about every 10 games. Now, it's almost impossible to get a high score, you know by the first few moves, and they don't let you just start a new game. It's torture and I give up. I don't like games but this one was really fun because it was not a point and shoot or anything, more like chess for slolerners.
