Recently I played Spelunky and noticed that there are situations I'd definitely call "unfair". For example, when exploding frogs get tiki-trapped right into a shop, or the Black Market entrance is behind a shop so you can't avoid bombing it. First I was kinda angry, then I thought how it's kinda what makes Spelunky work, that it's cruel and doesn't care. Do you think unfairness can be a design-choice and that it's maybe not in all cases bad but actually adds something to the experience?

yeah i think it adds a sense of reality to a game… ive been fucked over by shop keeper AI randomness and other odd things in spelunky that felt unfair.. but i just said meh and started a new game.

im not a fan of this in isaac though… thats why i dont let you get killed by taking a pill that would lower your life if you only have 1 health..
