Need help improving number guessing game

Spent a bit more time looking over suggestions and working out some
annoyances.

This is basically finding a balance between being annoyed by prompts
and being annoyed by having to quit and restart. Given the sorts of
people who will play this longer than to find out how it works are the
sort of people who find spreadsheets and powerpoints and EVE online
fun, I'll go with prompts.
