An excellent entry, one of the few I completed (with 7 star charts) and one of my favorites so far!
There's obviously some unfinished stuff, like the missing climbing animation or the crouch/slide going through the floor, but it didn't detract from the experience. At first I thought the jump was very abrupt but as I got used to it and left the initial small corridors, it got better. Though I struggled with the swing to the very end. There were a few frustrating moments, like the tight S-shaped corridor involving temporary platforms and lava, but overall the difficulty was pretty well balanced. The movements were interesting and worked well together.
What I think I loved most was the mood. The vibes were just top notch, with a special shout-out to the giants in the forest of pillars. The soundtrack was great (though it didn't always loop seamlessly, even in the latest version). The different areas really felt distinct and I could easily wrap my head around this space, where I came from and where I should go. It really felt like a metroidvania!
I also liked the idea of divesting yourself of your armor in exchange for regaining your innate abilities, but I was expecting the dragon to also lose the helmet at the very end, to symbolize being truly set free. Alas! It's also a bit of a missed opportunity that losing your armor doesn't factor into the gameplay somewhat, but that can be an idea for a post-jam version ;)
Congrats for a job well done!
