This problem wasn't entirely clear:

> Casting each of the spells in the set is finicky and doesn't always succeed. A cast succeeds 20% of the time and is independent of previous casts. I need 3 successful casts in a row to summon the animal familiar. > What is the probability that I summon a familiar on my first try?

I tried inputting the answer as a percentage with "%" and as percentage without "%" before I tried inputing it as fraction and was able to proceed.

It'd be a good idea to indicate what format the answer needs to be in.

I imagine they agree and aren't satisfied with the interface, but can't give it any more of their time. I take the impression they were more concerned about finding a novel and beautiful way to present statistics, and to transfer some of their passion for the subject to the reader, than creating a usable piece of software. (For instance, when they describe coming up with entirely different stories and casts of characters, repeatedly. Clearly the story is what is important about this project to them.)

Personally I've never made it past the first paragraph of a story without deleting it, so I salute them for shipping _something_.
