Yo this goes out to all hollow knight fans who want to play similar games!
I am not far into the game yet, but i recommend the last faith!
Its also a side scroll metroidvania with the kinda cozy/depressed vibe and an infection/abandoned world kinda trope.
It has a pretty similar fighting and playstyle, great art and nice music.
Its more dark than hollow knight tho, its usk 16, has some gory stuff (pixelart so not THAT bad) and overall is really gothic so be aware of that!
