I like that you started allowing people who can't afford premium packs ways to get premium cards. That is a big step in the right direction. However, I still think the old PVP system needs to come back as the new one is just a long boring slog battle after battle.
Quite frankly, this game is just stale after the first few campers. With the lack of quality you are forced to slog your way through an unsightly amount of campers, and after a while the whole "dodge, eat, grow" concept is just arduous.
I have to say, this version is worse than the full one by a million miles. Because it is flash it lags soooo much, rendering the game basically unplayable, but the game also lacks the precise hit detection that the full game has, meaning if you so much as touch a line even with the corner of the triangle you lose instantly. The movement speed is also about twice as slow as the first level in the full game, but the incoming shape speed is the same.
Wait a minute, you mean if you auto fight in the arena you will eventually die from idling? I do realize that the game was designed not to idle, but perhaps a warning should be placed on the auto fight button as it is quite annoying to leave for 10 hours at a time and find out you only went up one rank because you died.
The stadium needs a bit of work. I can't count the number of times I have lost races because for some reason after I jump I slow down, even if I am still holding R. Same goes for boosting.
I am still not sure how to back up my save file. I allowed hidden folders to be shown, but I cannot for the life of me find any anti-idle folders from either my computer or from the start menu.
Honestly, it gets to the point around the 3rd zone where you just don't even want to play anymore. There is really no hook to keep people playing, and the blood wolves with the poison potions just make it a pain, because by the time you get to them you are so used to dealing massive damage to win battles in a few turns and you go down to having to drag out the battle forever until you win.
