I join the others who already commented about the game. The mechanics aren't intuitive. We are taught through gameplay that we absorb light from things, so our brain says "yes i want to absorb". But actually those things are also ennemies, so you want to avoid them? And the platforming aspect is a bit tricky in all that darkness, even if I get it's the point to be in the dark.
But like others said too, it is visually pleasing and charming, and the game actually works, no bugs or anything on my side!
