And... the cost of 'experimenting' becomes really costly here since you have to reset your progress once you realized that your strategy won't work (since the crystal can only be gained through first win of a chapter and PvP (and you won't get any PvP point if you lose)). This becomes a rather money - oriented game than a strategy game :/
The shortcut 'A' for fallback and 'D' to push forward is a bit non-intuitive. I kept accidentally pressing 'A' when I mean 'D' because my brain keep telling me that A stands for Assault and D for drawback. I think an arrow would be better, or maybe C for Charge and B for Back would sounds good as well.
How sad it was to see a rather popular game (at its time) is now dying because of an unsuccessful sequel. In my opinion, the sequel is released too early and too focused on premium item which makes the player quickly lost their interest on the game...
Some heroes had a kinda useless skill. For example, Grant, The General's Red Whip increase the DPS of all heroes by 25%, but it kinda pointless since at the time, Grant dealt 54% of the overall DPS, while the earlier heroes just did 0.005% damage, so a 100% increase to Grant's damage will worth a lot more at this time. I think this problem need a little more serious attention...
WARNING, THIS COMMENT CONTAINS A SPOILER. IF YOU INTENTS TO SOLVE ALL THE PUZZLE BY YOURSELF, DON'T READ ANY FURTHER. YOU HAVE BEEN WARNED!
Okay, this indeed an interesting game and the puzzles are interesting as well. My only complain is that some of the puzzles are "unnecessarily" hard. I mean, for example, the morse and the braille puzzle are actually easy. The hard part lies on recognizing it as morse and braille, which need some guessing (or past experience about the code) and involve no logic, which I find kinda annoying. So I think you need to make the game more "self-contained", which means all the information we need to solve the puzzle should be in the game. Aside of that, the game is really enjoyable and nice 4.75/5
With the new evolve system, the importance of fame has increased significantly. It's really unfair and unfortunate for those who can't participate in world boss because of time zone problem. There should be an alternative way to gain fame. Maybe make it a daily reward, or arena reward, or maybe you could gain some fame by sacrificing cards, or anything...
If you think people will spend 1000 dollars in a month for the prepayment reward, you really have lost your mind.... Believe me, if you cut down the number to a rational amount, you'll get much more than you currently get. And it seems the chance to get 6 star cards via points draw has decreased since the daily log in rewards appear (I hope it's not true but just a mere bad luck of mine, but if it's true, then congrats, you have lost my respect).
I'm quite happy that this game kept itself at pay to win rate, and not go as far to pay to play. (with exception for thief stronghold, I have hard time with my plunder target x_x)
