This is very cool- haven't got through all of it yet but it's quirky and atmospheric and generally the sort of game a lot of streamers like to play. The intro was a nice touch and made me expect a walking (flying?) simulator, so it was a good surprise to get some platforming.
One thing I wasn't too keen on was the heavy reliance on a single background texture which looks like a cross between ancient runes and intestines (your screenshots show how prominent this is).
Minor criticism though, look forward to seeing more!
