I just wanted to gush for a minute about Mark of the Deep, Tombwater, and Hunt the Night. All of them are top-down (or isometric) exploration games with eldritch horrors and difficult combat. I'm terrible at "real" souls-like games but these top-down games are definitely scratching my itch.
Mark of the Deep has an isometric view and more modern graphics (compared to the others). The map is a set of interconnected regions where each region is a labyrinth of hidden paths. This one is very easy to get lost in but I think it's well-made. It does a good job of letting you unlock shortcuts as you progress so you don't have to backtrack too much after dying and restarting at the last save point. It took me ~20 hours to beat.
Tombwater is a new game that feels more like A Link To The Past than Mark of the Deep. It's a spread-out open world with optional bosses and 32-bit graphics. I really like how it lets you disable the "corpse run" mechanic that is common in souls-like games. Like I said, I'm terrible at "real" souls-likes so this is a huge selling point for me (Mark of the Deep doesn't have corpse runs either). I'm ~8 hours into Tombwater and I'm really enjoying it.
I've only played the demo for Hunt the Night but I absolutely loved it and since there was a bundle with Tombwater, I bought it on an impulse. I'm looking forward to playing it after I beat Tombwater though.
I know Tunic and Death's Door both have great reviews and souls-like aspects but those are too cute for me. I don't just want a zelda-like with difficult combat, I need that eldritch horror aspect to really scratch my itch. And I'm not sure about Mina the Hollower yet. It isn't nearly as cute as Tunic or Death's Door but I don't know if it's all that "dark" either with that artstyle.
Anyway, if you know of any other top-down/isometric action games with an eldritch horror aesthetic, please let me know. I can't get enough of them right now.

As a counterpoint, I've not had any problem with the weapons. I went with the whip though. I think there are 4 or 5 - you pick one to start with and unlock the rest throughout the game.
It does take a minute to get the timing right on the burrow mechanic because you do jump up before diving underground and you're vulnerable during that jump. I grew up with the NES though, so that old school style is what I got used to. I learned how to swim through the underwater plants in TMNT; I beat Link's Adventure without the...cheat thing I can't remember because I'm old now... Game Genie.
It is far darker than the art style let's on though.
