Alright, this game was very interesting. Definitely enjoyed it. Mystic Thief and the Protag were very cute, however - I can’t help but notice...
What if this game didn’t have a true ending? Just a happy ending with anyone? Even if it is just a game, it makes me feel guilty for everyone else... I dunno, it was enjoyable, but I really liked Walter, haha.

Amazing game!

I love the whole look and feel of the game. The characters are well drawn and the plot is nice. So far I haven't been forced to pay to see the story like many other games.

im just truthful ,

Here’s the thing

The art work and story line is beautiful and I enjoy it very much.
I will say though it is hard to get coins. When you watch videos, you may only obtain 300 each time with a limit of 5. The surveys offers more. But every time I take a survey.. I NEVER GET MY REWARD. I’m disappointed honestly. Save your time if you don’t want to spend $ and play another game.
