I got bored really fast. The combat is way too simple. Basically if enemy flashes red press one button, if it flashes yellow press another button. The combat is so fast that I can't see anything, I just dodge & attack continuously and hope for the best. The pacing is weird, there are rooms with no enemies followed by rooms with swarms of enemies that you get bored fighting for so long.
The map is weird, while it looks beautiful and each room is almost unique, you get lost very easy because it's hard to remember so many unique rooms. Exploration is barely rewarded.
The pixel art is absolutely gorgeous and the only reason why I bought this game.

Awesome :)

Pros:
I love the atmosphere.
I love the art.
I like the soundtrack.
The story and lore seem cool.

The combat is too fast.
The enemies move too fast.
You move too fast.
"Levelling" is almost entirely meaningless.
Healing is tied almost entirely to the "parry" mechanic, or spending karma, but before I got a second weapon I was able to make it so I didn't have to spend karma, so that was an f-ing lie.
The "parry" mechanic gives multiple frames of visual cue, but seems to have 1/2 of a frame to execute it.
The difficulty setting just reduces the number of enemies from "I can't see the floor" to "makes sense" and allows you to heal. Slowing the game down would have been a better way to balance it.

After 2 hours I hit a boss the homonculus that is just nonsense. Split-second everything, lenghthy AoEs, tiny arena...
I'm very sad to say that I have like 40 more years on Earth, and banging my head against this game isn't worth it.

Yet another game that thinks "If you're inspired by Dark Souls, you need to be unreasonably difficult."
From makes games that punish you for mistakes, not games that pummel you for playing them. Well, aside 2. DS2 is trash.
