I respect the ambition on display, the fact that many of the assets are clearly custom made and the inclusion of quite a lot of dialogue and lore for such a short period.
In terms of improvements, I would make some of the dialogue skippable or able to be sped up. This was most apparent at the "Story tomb" event. At some point, the bit overstays it's welcome and unfortunately, there's no way to exit from the dialogue.
Otherwise great work in doing so much in such a short period
