Game starts straightforwardly, with a fun minimal blocky style and nice clues. Then the “solution” to a puzzle gives a paragraph of text in characters that are Japanese or Chinese!
I’ve played Japanese-only games where only the instructions and flavor text are in Japanese, so you don’t need to know the language to solve puzzles. I’ve played games where puzzles require matching Japanese characters but you can do it based on the pattern, without understanding meaning. This is not either of those. This is a case where if you cannot read the text for meaning, you lack a needed clue. This game should not be listed as being in English.
