Nice game.
I missed first part of the relic and didn't know what to do, but have already found solution in the comments.
The music is a bit disturbing, but it matches the theme, so it's fine.
The color choice is a bit questionable, but the drawings are good. Maybe it's because of the contrast. You can choose a color palette for future games on https://lospec.com/palette-list or similar sites.
I really enjoyed the overall adventure feel.
