Are the pieces given entirely random so that each time it is played the varieties of the pieces and their orders are different (except for the puzzle levels)?
For at least one level (the first puzzle level), I found it is impossible to get 3 stars without using a talisman power. Is this deliberate? Can that level be beaten without using a talisman?
Which other levels cannot be beaten with 3 stars without a talisman? For example, for level 17, no matter how many times I restart the level, at some point midway through, I will always get a string of "bad" blocks so that it was impossible to pass without a talisman to convert some pieces. I worried that this is by design and is basically a paywall, given this is a freemium title.
