In levels with bee bombs, the boost "Bee-B-Gone" wants 34 Gems before the game but 33 Gems in the game. I think it is not fair. That should be 39 Gems or more in the game, or less than 30 Gems before the game.
In levels 43 to 114, no more challenges are there except "Reach level 7 in Dragon Story" or "Play 40 games in word search". So is there not any challenges except finishing levels?
