5 stars: I'm liking what I have gotten through so far, I've gotten a decent collection of cards on the first session. Made great amounts off trades from the occasional times NPCs pop up. Update: I've been having great chances on getting legendary cards, I've been playing this more than I was expecting. I purchased the $9.99 CAD bonus (for removing ads) to help support the dev.
5 stars: I like it. It's a way to kill some extra time, without having to babysit it constantly to stay
4 stars: Nice simulator, pretty easy to get a handle on what to do, only bummer is at a certain point your stuck waiting for sales, add a minigame or something using some collected cards, because I also noticed as you go you have tons of basic ones. All in all a nice little simulation of a store, great idea for cards and selling and trading.
4 stars: Decent game to play, when you got time to kill. Solid gameplay in my opinion I haven't encountered any bugs or issues that I can see, no, I would say something to add would be an additional option would be to do card bidding as a mini game when you get a rare card.
3 stars: Not a bad game. I thought it would be ridden with ads, but they're all optional. Wish there were a way to get the auto upgrade with gems and not ONLY through paying $6. Also found a bug with the achievement for unlocking the 3rd room. I built every single table for cards to sell and haven't got any achievement for the 3rd room.
2 stars: Love it but has issues. Ever...
