Pretty decent! Didn't really entice me to continue looking for secrets after doing the final area, but I ended with around 20 eggs found. The item abilities are pretty cool and each have at least a couple different ways to use them.
I think the minimal art style and almost entirely absent soundtrack kinda works against itself a bit because everything feels very samey (outside of the final area really). That would be less of a problem if the game didn't require so much backtracking and tedium, if you die (sometimes either from exhausting your HP or otherwise there are one hit instant deaths) you will be warped back to the place you last saved and then have to trek back across several rooms to get to where you were. That does often mean having to redo platforming or puzzle challenges, over and over, since most really don't seem to unlock shortcuts or means to circumvent. There is a fast travel hub but it's a secret unlocked after finding some number of secret eggs, and there's then a secret that will teleport you to the fast travel hub you can use once you collect more secret eggs (I did not know about this until I beat it).
Another art issue is the use of spikes as obstacles, they're very often not clearly presented as being dangerous and background elements can also look like spikes but aren't. Often times found myself trying to avoid something that wasn't harmful, or thinking something was safe when it wasn't. On the positive side the lighting and smoke effects can be very impressive, though honestly set me up thinking they'd be more present.
The controls have some issues too, primarily around abilities. Rather than them each being mapped to different buttons, you cycle through them individually using the shoulder buttons. It makes things feel slower than they should and sorta impedes creating a rhythm. They give a lot of leeway on your character falling off of edges, but that can work against you when you need to quickly (like being chased) fall down. There's a few times where you have to fall into holes about the width of the player and it would refuse to have me go down.
I played it through PS+ so can't complain there, but the $25 asking price is way steep. It's pretty well a 2 hour long game but with all the backtracking and repeated rooms to clear that can about double. It seems like a decent enough recommendation for $5-10 but man $25 is rough, there's just not enough meat here and no real Wowing X Factor to latch onto. Ultros seems like a more compelling recent metroidvania that could use some more eyes on it.

I did every dungeon and probably just about every boss so that you don't have to! Because you shouldn't.
A game that probably should've had like 1/2 the content so that more of it could have been focused on being meaningful rather than uninspired tedium. Lacks the feeling of intentionality from their prior games (enemies and bosses are placed willy-nilly across the game world) so you will be seeing a lot of similar faces. They took a sort of Skyrim approach to NPC's and factions where you can now be allied with anyone and everyone simultaneously, regardless of them being entirely opposed to one another, which makes your involvement feel pretty flaccid. Your choices at least culminate in a 10 second cutscene, half of which are just colored differently, and afterwards you continue like nothings changed.
At least they finally figured out how to make shields good, I guess? The art and character design is good as usual, the music is fairly average, and they managed to have your human characters not look terrible.

I think this might be where I bow out of FromSoft's catalog unfortunately. I started with Demons Souls on the PS3 and their Souls-esque series has evolved from an experimental and creative adventure game with great vibes, to a fairly mediocre action game entry propelled by great art direction. Sorta feels like they're out of ideas, with the exception of Radahn each boss is just your typical action challenge without much of interest. Command your two brain cells to dodge an attack (maybe two attacks if they're feeling daring), hit once or twice, repeat. They took maybe one break away from this model to take another crack at a Demons Souls boss (this time Storm King) and as usual it's just a worse imitation.

"This is my favorite spot where to play. I like it because the view is pretty" Sea of Stars, 2023.
A masterclass in terrible writing. The main duo are missing any personality and instead are just generically "Hero", any dialogue or flavor text is dry and uninteresting. Combat is okay at first but has almost entirely no evolution; what it starts as is what it stays as and you'll be doing it A LOT.
The only reason it got this high of a score is because the 2d art is nice and the music can be good. This being anywhere near a best of list was laughable.
