This is a dark project!
Very cool! The game is fun and the flow is nice. The dialogue is a bit slow so the skip is very welcome - nice narrative.
The downside of the nice and continuous flow - I basically hugged the walls of each level and just looted. I dont know if this was the intendet way but it felt a bit like I was optimizing the fun out of the game (I said the quote uuuh cool).
The presentation is amazing. Nice environment work and characters. Particularly enjoyed the pick up animation (inspired by Blue Prince?) and the loot presentation in general.
The theme works narratively and moves the story but playing the game I never felt like I was generous. I am not so emotionally attached to the loot since it is so easy to get and kinda "not special" since there are only a few items and these are scattered everywhere. And then I have no choice and no gameplay in giving it away which just makes it another button-press for me.
Also props for using your own engine :D Great work and keep it up - I want to play the "Mammona Metal Age" soon!
