I like the character design and the game is not complicated. What bothers me is the gems. We have to watch ads/download app/do survey to earn gems, I downloaded this game to play this game (obviously), not watch some random ads that has nothing to do with the game! Options are also very limited without gems, each options could cost around 10-50 gems, plus we get limited amount of gems each day. A suggestion: Add game events to earn rewards
