Tutorial is broken or is missing basic core info. It says I "won in 1 turn" but I never did any damage to the enemy. I "won" the next two battles without doing anything other than picking up cards, and then in the third I did the same but this time magically the enemy took no damage for no reason.
The dagger card could never be used despite me having the cost avaialble. Clicking does nothing.
Buying a second dagger said it would upgrade the card but it had no effect.
Either there's a lot of bugs here or tehre's some fundamentals of what the heck is going on that the tutorial desperately needs to explain.
