HACK9 by wahiko is a relatively old Cave Story inspired platformer that is more difficult than it should be. I liked the basic gameplay and the variety of music, but grinding shouldn’t be a core requirement for getting through a Metroidvania. Additionally, there is so much Japanese dialogue in the game that it’s easy for players of other first languages to not know what to do next.
For months it sat ignored on my hard drive after I gave up on exploring the game’s world, since I couldn’t unlock any areas beyond the default availability. However, one dedicated player (nintendofan100) made a video walkthrough, with aid of some helpful comments on the Indiegames.com Blog post on HACK9, which has made the game much more accessible and has allowed me to appreciate the game more.
The video at the top, however, isn’t part of the walkthrough linked before but was chosen to present how confusing the game’s language and design barriers can be and because it contains the game’s audio (unlike the walkthrough).
