I dislike most multiplayer games here, but this one was fun to play for the badges.
The fights don't require energy and there's strategy to what you play, not just mindless autoplay.
Being able to try out some different cards in the dungeon was fun.
The devs replying to comments is also nice. (It's working on firefox for me, btw.)
I won't continue since I don't have the time or money to invest, so I can't rate how much it will force you to pay to progress later.
Thanks for an honest and helpful comment, mxlxe, glad you enjoyed the time you played! Hope to see you back soon!
