We've got the first real gameplay video, it was taken down by the author but you can find it on this channel.
https://www.youtube.com/watch?v=_BH2nVEdFGw-3 Relics can be equipped. No armor pieces apparently.
-the stats are seemingly only ATK and DEF.
-7 weapon categories. It looks like there's 4 weapons in each of them, starting with "Ordinary" weapons, for a total of 28 weapons. Swords, greatswords, whips, rapiers, lances/spears, fighting gloves, and short sword + shield.
-A deeper look into Arcana tarot cards. Only one of them can be equipped at a time.
They were given to Rose by Sypha, who is stated to be dead by the authors of the video. The first spell is in fact a burst of fire, and the related card look like Sypha.
There's a perk system and subquests (for example defeat a number of enemies in a certain way) to gain points and upgrade those spells. Each defeated boss will grant you the card, a spell, a progression/movement ability, and often their weapon too.
For example beating Jean D'arc rewards you with her burnt greatsword, an AoE fire spell, a key to open a portal, and an halo of light ability to break "Chaos Shards" walls.
-You don't start with the Vampire Killer, that's in Trevor's pocket of course. It's not clear yet why Rose and her father go separate ways because the intro isn't shown in full.
I'm not sold on the gameplay, having lots of weapon options is cool but is there more depth to the system? Are the 3 relics enough to make different "builds"? Both in systems and in gameplay it looks more similar to Blasphemous I and II than Igavanias.
The writing seemed passable to me, but it is worrisome that not even 2 minutes in and they are already depicting the Bishop as greedy. I hope the Church isn't the villain or a negative force like in the Netflix series.
Sypha being dead is also lame, hopefully she appears as a spirit and her death plays an important role in the story.
There are also some worries that Rose might be the only child Trevor had, which would break the Lament of Innocence family tree, but we don't know yet.
