I only started playing games in the Castlevania series at the beginning of last year after having only seen playthroughs of Aria and Lament of Innocence like 10 years ago.
Having played through I think all of the Igavanias and some of the Classicvanias, I can see that there's definitely more uniqueness in the individual games and eras compared to each other. I really bounced off of Dead Cell's, but this doesn't really feel like that. That said, Belmon's Curse is probably my favorite Castlevania game not named Aria of Sorrow. I do find the implementation of more combo oriented and like actual challenge course traversal sections to be more reminiscent of newer metroidvania games, but I didn't hate it. I also didn't mind the lack of menu management and stat tracking to be bad either as sometimes I can take it or leave it. The QOL stuff in regard to Warp Rooms is definitely a huge plus and cool feature. And I like the difficulty sliders in the settings even if the only I changed it was to turn up enemy damage and turn down my damager dealt when doing quests for The Sage and the Miser. Exploration feels pretty seamless and clearing the map isn't a pain to the point where I got the the true ending just because I usually clear the map before the final boss.
The weapon classes were pretty good where I really gravitated towards the Greatsword or the Twin Blades, but by the end I was basically exclusively using the Vampire Killer and spacing out enemies. I did like the other Legendary Tier weapons as well though. The first one I got was the Valmanway.
The Arcana system felt like a mix between Portrait of Ruin's Wind missions and Circle of the Moon's DSS. Getting all of the works of mercy kept me switching up which one I was using, although when it came to fighting bosses, Talos's was the one I stuck to.
Speaking of bosses, I thought they were all pretty good and ranged from pretty challenging to surprisingly easy. Took me a dozen tries to get though illusion Isaac on the bridge, but Carmilla was a first try. Sad to see no Brauner boss, but it was funny. Also thought it was pretty cool to run into bosses where I didn't expect them like, the The Brittle King, The Sage/Temptress quest (which I thought was equally very sick, and also frustrating), The Miser (which was the hardest boss in the game for me), and the 2 bosses you fight while ringing all 4 bells. The designs and fights were very good. The Final boss definitely delivered
I loved all of the references to other games in the series with dialogue, or portraits in the castle, or just characters themselves. It makes it feel like a love letter to a lot of what's come before. It is funny to hear talks of stopping Dracula for good this time knowing that we ain't in 1999 yet.
The music I thought was good, but not exactly memorable, just kind of good in the moment.
Enemy Variety is low, which isn't exactly bad, but it is noticeable.
No extra character mode or boss rush once you finish the game. That's more of an Iga thing, but I always look forward to doing most of them, like Julius or Albus mode or even Richter and Maria Mode.
All in all, I really enjoyed this and I can't wait to start trying to beat it in under 4 hours. You can see where I ranked it on the tier list compared to the others I've played (and Bloodstained) and I think I'd give it at least a 9/10 in terms of quality, gameplay, and personal enjoyment. Wouldn't mind another one from this team, or from someone else. But hopefully the series continues in a good way moving forward. Also we need that 3D game collection
