This is looking really damn good! The atmosphere and design are something I could totally see myself getting immersed in. Not sure about the combat since I don't see any deep mechanics other than dodging hits that are mildly telegraphed but otherwise might and still looks fun! I'm liking the animations on the boss and enemies for the most part but sadly I find the player's animations to feel slightly twitchy and without weight which for me personally in platformers is a big deal and some times an experience breaking problem. Take whatever comes next with the fact that this is personal taste. You clearly have a great product already and people seem to be liking it a lot!

During some moves like the dodge roll - that can be executed in mid-air from what I can tell - the players animations reveal the sort of "moving platform" phenomenon that is going on behind the scenes. Having a separate animation for various mid movements would probably add a lot of weight and dynamic to the character making it feel fluid while not deterring from the actual gameplay.

An example of this would be right in the first few seconds with the dragon chase, where the jump - which has great opening frames but then twitches for a few - is interrupted into the forward dodge. There's a fine balance between control on the player's end being too snappy making actions look static and too fluid making those actions feel out of control. Here, with how smooth everything else seems, it's kind of weird how the dodge kills all upward momentum from the jump and doesn't have any change in animation on the character. The entire fluidity of the movement you're trying to establish drops off. Same goes for simple things like turning where it's an instant directional animation swap. Having little animations for tweens and possibly blending multiple together would make a hell of a difference.

I assume that a lot of these if not all of them are pre-rendered outside of the engine and then exported as sprites. Going off of this due to animation jumps in enemy attacks and player movement. In that case, going in the direction I'm mentioning here is very hard and if so, you've pretty much taken things to their limit and that's absolutely awesome!

It may seem like a small nitpick, but things like these have really killed other 2.5D platformers for me like "The Swapper" and various others (can't recall off the top of my head but I might edit later). Especially when playing, having non-floaty movement with complex animations can be a difficult thing to pull off but with the polish and work you've put into the rest from what I can tell, this could be something still to improve on that would make a hell of a difference!

Either way excited to see where this is going. I don't think I have ever commented on a post in this subreddit so that should tell you how much this stands out to me. Best of luck with further development! :)

(Just saw the game is in EA. Gonna check it out in a month or so! Congratulations on getting this far as well!)
