1. Didn't shuffle the 'khan' blanks into the deck. It appeared only once. Checked the deck and the blank wasn't in the deck.
2. Yes, very weird behaviour... so the deck gets smaller and smaller when I played. I used the 'khan' cards to stop the 'bleeding' as much as possible, but it was impossible not to get strikes. Glad to have a lot of extra HP boost and red 'health' pylox charms, so that my HP could get back to normal quickly.
3. The ┓tile disappeared to the right of the starting tile while I walked over the tile. I ignored it as it was the same annoying thing like in the previous two or three levels. I am very sure that the avatar was standing on the right portion of the path. I know that the goal was only to reach the treasure trove, but the game stopped when I was on the way.
