Played the demo of this game and ended up loving it so much that I bought, one of the best game purchases I've ever made!
Having now gotten all the achievements in the game I think I can judge it more fairly.
Pros:
-fulfills that "number go up" itch when I have it
-coming up with strategies to get further is very fun
-I've played for hours before I got bored or could no longer think
Cons:
-there's not an endless mode (not that I think you could keep endlessly progressing at the current moment)
-some strategies become obsolete the higher your rating quota is
-some card sets or categories have such a small number to pull from that they're difficult to use
All in all, it's a good game that's still seeing updates and I look forward to see what else comes from this developer
