Seven-question trivia practice: which categories should we add next?

I’m B.Liu, the maker of Krillion Coach.

It is an open-answer trivia game: type an answer instead of choosing from a list, watch a pixel fish descend, then review the answer sheet. There are daily and free-practice modes, an optional 25-second timer, and no account requirement.

The bank currently contains 14 original prompts. The answer lists and scoring are our own: this is independent of the official Krillion game and does not reproduce its daily bank or rarity algorithm. Our rules are at https://krillion.space/guide

I’d like feedback from people who enjoy short browser games:

• Does the optional timer help, or would you start untimed?

• Which category would you most like us to add—geography, films, science, or something else?

• Is the answer-sheet review clear when an answer is unlisted?

Thanks for trying a dive and sharing what you found.
