9 Years of Shadow is a very intriguing production with an excellent, old-school audiovisual style. However, it is definitely a title aimed at fans of metroidvanias, who should consider it a must-play. Other players may complain about the high difficulty level, formulaic structure, and repetitive gameplay. Nevertheless, the developers have delivered a technically solid and polished game that is undoubtedly worth attention. Play it if only for the soundtrack alone, which is truly outstanding.
