Does the continue cost $0.99 every death? Or, is it a one time payment that unlocks the option to continue?
I don't like the continue idea, mainly because I think perma-death games should stay that way . But, I do like the idea of $1.99 per character.
Maybe you could add certain perma-buffs/items that could be available at the beginning for a cost (e.g. $1.99 allows you to also start with a random spell every adventure, or $1.99 unlocks such and such an item to begin with every adventure.
I have a lot of ideas from playing a lot of different rpg's, but I don't know if you want to hear a bunch of them.
I really enjoy this game, though. I found it last week and have played probably about 30ish runs; I've only made it to 36 on the path
