I'm fresh off reading patch notes, the new room types have me so hyped! Warrior seal change is fantastic, I always understood logically that it was impactful, but it never felt as noticeable as even the Duelist's level 1 talent granting Sheild.
Expounding on the new rooms, I really hope the barrels are intractable like they are in Remixed PD, the only other PD that I can stand to play after Shattered. The double new blue flames look really interesting, I wonder what they do? Maybe the skelecages are more than decor too?
The bridge to nowhere looks sick, and the dark crystals in Demon Halls gives it a really thematic claustrophobic feeling, while also adding tactical opportunities and pitfalls.
I love the new entrance rooms. Hell, reading this dev diary, I'm realizing how much I love room variety and how much it adds to the dungeon feel of the game.
Cleric buffs are great too, they've felt weak, but I haven't played them a ton.
This is just my very first impressions, I plan to report back once I've tested it :)
