From GamesReviews:"A dark gothical fantasy with heavy concentration on puzzle solving and platforming in this Victorian 2D to 3D Metroidvania will make you spend your day solving the lore."
Dive into the best Metroidvania games on Steam, from hidden gems to top-rated classics, and embark on unforgettable adventures!
Good list, and kudos to having a list-article where everything is listed on 1 page.
Nine Sols looks nice, and also a bit similar in style to Bo, Path of the Teal Lotus, which should also be a good game (picked it up a few weeks ago but haven't played it myself yet ... )
Neil writes: "If you've worked on the likes of Bioshock Infinite, on Grand Theft Auto IV and Assassin's Creed IV: Black Flag, then you probably know a thing or two about what makes a game tick. That's the hope as the newly formed indie studio at Cut to Bits announce their riveting and dynamic metroidvania-styled debut title, Venture to the Vile."
Not sure about the animation looks a bit stiff but the art style and game world look great, really distinctive.
The setting and aesthetic look different than most metroidvanias but other than that this looks like a paint-by-numbers copy of everything else that's been done a million times.
