Main changes which have been made in game so far:

Increase the number of days between enemies from 4 days to 5, totally from 16 to 20 for each floor (problem: it was too hasty to meet an enemy for every 4 steps).

The initial Max Mana of both sides takes1 instead of 0 (problem: it was a little boring because there was barely nothing else to do at the start of each combat).

Increased a Fast mode which can speed up the animation (problem: a combat took too long because of the animation).

You can use a more powerful hero skill once in each combat, rather than a mini one in a single turn. (problem: hero skills seemed to be weak, especially compared with ones of your opponents').

All decks of heros has been greatly improved. We decrease the number of non-effect cards and improve remaining non-effect cards. Besides, many powerful cards have been added into initial decks. (problem: the initial deck is too weak).

Now you can gain more benefits in each event. (problem: you gained so little in events that your deck was not good enough to fight against enemies. It is difficult to complete a game).

Lower the degrees of difficulty of all levels (problem: it was difficult to have fun).

Adjust the values of many cards (problem: the balance among cards).
