I'm not sure where else to put this, but I feel like I need to rant about this, because it's a case where widespread reputation is polar opposite to how I feel.
The thing that I am absolutely the most baffled by about Nine Sols is how heavily its visuals are being praised. As someone who's absolutely obsessed with drawings/art/animations/sprite-work and things like that, how poorly drawn and animated it is is by far the biggest weak-point for me, personally, yet it seems that everyone else agrees that it's just about the only untouchable aspect of it (I've seen more criticisms about its mechanical polish and storytelling, with the caveat always being that nobody can deny how beautiful it looks).
Yes, there is A LOT of animation and the guy clearly poured his heart into putting the work in and having an impressive "quantity" of animation, and he arguably has ambitious ideas when it comes to setting colors, presentation concepts, and art direction, but fundamentally, it also looks like it was drawn by an amateur on Deviant Art who isn't very good at drawing basics yet and is still learning, in my opinion. The guy does not appear to have much understanding of squash and stretch, fluidity, how to convey impact, how anatomy looks in motion, and things like that. In fact, it appears that the grand majority of the characters/enemies (especially larger enemies or non-humans) are just stiff/clunky blocks with appendages that are independently rotated at the joints like ragdoll action-figures to convey movement rather than moving like how things would actually move (or how they would unrealistically move in exaggerated but more dynamic/interesting cartoonish ways). It's perhaps flashy because of all the action that's going on, but it's flat, robotic, and completely non-dynamic, in my opinion.
The main character art/animation is moderately better (and the IDEAS for the moves are at least pretty cool), but it's still pretty lacking for me, personally. If someone I knew did something like this, I'd be proud of them, sure, but not a professional artist. I would argue that the large majority of critically acclaimed 2D indie darlings look significantly better than this, art-wise.
It feels like I'm alone on an island with this take, and I don't want to be mean to the guy because it's just a passionate guy doing their best, and I'm not saying I could do better, but man do I feel strongly about it. It just looks so ugly to my eyes but it seems that nobody agrees.
Edit: I mean, look at how these bosses move and look, it's gross. Not only does it look like a child with limited understanding of 3D perspective drew it, but it moves as if they cut out the torso and limbs out of cardboard paper and are just rotating them at the joints. How is the praise for this game's visuals so unanimous?!
(this one has more fluidity, but it still doesn't look good, in my opinion)
