Cool story. The fact that the hero dies is unique. The audio is alright, maybe some more sound effects, such as sword whooshing and a gibberish voice over over the text or even like text sfx would be welcome. I like the low poly art style a lot and the animations are pretty good.
The click to proceed however sometimes broke the cutscene flow. clicking too fast skipped even the animation, which leads me to believe the text is tied to the animation somehow? maybe using the timeline? if you did decide on interactable dialogue, maybe a dedicated dialogue system would've been a better design choice.
Overall, quite enjoyable, good job!!
