Keine's Expanding Class! — is a hangman-style word puzzle where you have to guess words letter by letter based on clues and a limited number of mistakes. The game is built on gradual difficulty: the further you progress, the broader the vocabulary, and the more unusual conditions begin to interfere with the usual guessing process. Vocabulary and attention testing Each round gives a hint and a hidden word that must be spelled out. Mistakes are limited, so you have to choose carefully and avoid guessing. The challenges become more challenging over time: rarer words appear, and additional mechanics can alter the familiar rules and disrupt the flow. You can customize the wordplay — choose a Touhou theme or focus on common English words. The game rewards attentiveness and knowledge, but also leaves room for recovery: special abilities allow you to undo an attempt and try again as if no mistakes were made. Features of the game A puzzle in the form of guessing words by letters. Customizable word sets and topics. Several difficulty levels with complications. Abilities to help in difficult situations.
