@serrebi, Yep I noticed that bug too, I thought it was just because I was playing on the board game, but obviously it happens with the sticks game more generally.

@Enes, there are three ways raise your level in the card game.
First,  raise a level for which ever element you are.
Second you raise a level for any cards of an element you play and third (most recently), you raise a level in a different element if you have three cards of that element type in your hand.

So say you are normal type and you play a slap card. You get two levels in normal type one for the card and one for being normal.

You can also get cards that raise your level, indeed each type has level up cards that raise it  you play them.
So if your ice type and play cooling, you'll get one level for being ice type, one level  playing an ice type card, and one level as an affect of the card as well.

hth.

@Bigdog, I think the organization of the cards is not reflective of anything in particular at the moment accept that the table needs to be  layed out with card types in the different rows, and all of the cards of a given type in each row.
the blank spaces are just I suspect to do with how the layout and cards themselves are identified in the program and not indicative of anything.

@Staindadict, if I remember correctly to unlock the ice world you need to take the altnerative exit from the Hights, past the flying boat minigame. There is also the desert unlocked from the volcano if you pass the dragon scales minigame.

@Csm120, I hate pursuit on the pack ice. It seems the only way of winning seems to be hold up arrow and hammer the f key to grab any fish when in water. I think your supposed to only go into water to catch fish, however since avoiding pools of water also seems to take you  right or left and so not ahead of the polar bear chasing you, it doesn't actually do you much good in the long run.
The times I've completed the game have been pure luck, and how your supposed to unlock it goodness only knows.

@Enes, the grand council actually doesn't change any of your opponents. The reason the ray did so much damage is likely because both ghost and shadow are weak to it, and maybe your special defences were lowered  your enemy had previously played cards to raise their special defences. Gen generally in the grand council you will always get at least one type that your deck type is weak to, it's therefore a good idea to create a ceck that can handle them.
For example I have an ice deck who's entirely function is to freeze the opponent solid, thus even if they are something that is strong against ice, I stop them from going.
