Developer Builds Backwards Word Game Noillirk, Where Answers Must Be Recalled in Reverse

A developer describes Noillirk, a word game whose name is 'Krillion' spelled backwards and which is the third title in a family that includes Dive Krillion and Krillion Infinite. In the game, players answer prompts like 'name a fruit' by producing words reversed, which disrupts the brain's usual fast, forward-only retrieval and makes the task feel noticeably harder. Building it required curating a separate prompt bank, keeping rarity-based scoring intact, and designing the interface to signal the mirrored mode without a tutorial. The developer found that playtesting the backwards version revealed where the difficulty of the original games comes from, namely the race to retrieve less obvious answers. The backwards game ended up serving as a diagnostic of players' own word retrieval as well as entertainment.
