I've been partially watching development on this game ever since I saw a short on it and I'm very happy to see it fully released! I love my Rogulites and Vampire Survivors-like games are always simple yet fun. The art style is adorable and the music is great!

There are a few things I would like to note though:
Basic Arena runs are a bit too easy to complete and there's not much of a noticeable difficulty spike between the 3 Hazard Levels.
Achievements are a bit too easy to get/There aren't enough challenging achievements. I've only got 4-ish hours in the game so far and I already have all but 4 achievements (and two of them aren't even that hard with killing 50k enemies and dying 5 times).
Donation Box spawns are pretty scarce in The Club stage and nonexistent in Hell. This could be a design choice, but it makes coins pretty much useless in those stages.
Enemies do tend to spawn in walls and get stuck on objects easily, and weirdly enough can't go down the stairs of The Club.
It's a bit awkward not having an explosion Effect for the spider and that one legendary item (I forgot the name lol).
Jumping is nice but feels unnecessary. It'd be cool if there was a stage that has islands/cracks or something so you have to jump to get around and dodge instead of walking. You could also add more enemies/bosses that give you reasons to jump (like bullet patterns, charged attacks, etc.)
I wish there was some sort of Active ability unique to each character so you can have more of an impact on the game other than walking and choosing upgrades.
On a similar note, it might be cool if there were Character specific upgrades/items.
I also noticed a bug where if you unlock a skin on one character, it acts like that corresponding skin is unlocked if you click onto any other character. And for some reason they're all named Black Outfit except for the Default and White outfit.
I feel like there's simply not enough Stages, Bosses, and Enemy variety.
I wish there was a bit more lore and story! Doesn't matter if it's in the form of cutscenes or in logs similar to Risk of Rain/Risk of Rain 2 because I can aleady tell there's a lot of potential for a really good story!

I'm sure there's more I'd like to say, but I currently can't think of anything at the moment. Regardless, I do like this game, and it has so much potential once there's a bit more polish and content. I can't wait to see what's next!

Flock of the Seraphim in it's current state, although fully released, feels like it's still in early access. What's here is rather promising and the game has a great understanding of its personal aesthetics, but is lacking anything that really hooks you in and all in all feels rather bland after a few runs of gameplay.

I hesitate to say Flock of the Seraphim is a bad game, but it feels a bit underdeveloped. No tutorial, no dialogue or story, just dropping you into its Vampire Survivors-like gameplay and expecting you to have fun when its quite jarring and takes you immediately out of the game.
Everything feels slightly off, style is 100% prioritized over substance as there is very few actual levels and everything about the game is quite convoluted and confusing. I feel like this game needs bigger and better updates in the future to keep a consistent player base because right now it is really lacking in some sort of hook.

I like this game, I like the idea of it more however. I hesitate to say it's a bad game, and I see myself playing it some more but unfortunately as just something to do with my hands as a video plays in the background. Realistically I'd give this a mixed review if given the option, and if one of my friends bought the game I wouldn't deter them. But, there are better religious inspired vampire survivor likes that released in the same month shockingly enough so I feel like Flock of the Seraphim will eventually fall to the wayside as sad as that makes me because there is an essence of something special here.

It's a good game solid 6/10 but for the love of god do not 100% it, the enemies spawning on top of you makes it almost impossible to not hit a run.
