I started out really liking this game and happily paid 2.99 to go to the second level. Things went downhill when I needed a hint and the game required me to watch an ad for it. A game shouldn’t charge for hints if you’ve already paid for the game. Things got worse when hint number 1 suggested I do something I had already done. Then, because of the way the hints are set up, I had to watch seven more ads for hints numbers 2-8 trying to find one that was relevant to where I was in the game. Finally after watching all the ads and finding none of the hints helpful, I arrived at a screen that offered to let me skip the level if I paid $1.99. Are you kidding ?
Puzzles in this game are pretty fun and challenging although not always logical... at least as far as I could tell.... but the dev’s business practices are not so good. Three stars out of respect for the work that went into this game, but the way the hints/ads/skip option works deserves less.
Found what I think must be a glitch - in level 2-9 the wheel puzzle on the locker is frozen except for the outermost ring. The other rings will not turn no matter how I position the outer ring.
