While this game has a fun art style, interesting worldbuilding, and the main 'puzzle' of learning languages is enthralling, the stealth segments are... bad.

The first couple are short and sweet and to the point, and they're fine, but once the stealth parts of the game become puzzles unto themselves, they really stop being fun. I might pick this game up again in the future, but as of now... it was less that the stealth segments were frustrating when I stopped, and more that I could see them becoming truly awful as I got closer to the end of the game.

That said, if you're patient and really enjoy a fun 'gimmick' for a puzzle game, it's pretty solid.
