The tone and atmosphere are great as others have said. There is just enough of a distance between light sources that I know where to go, but it requires exploration to find and there's dark space that feels creepy.
I don't play much of this genre of game, so take what I say with a grain of salt. But I wasn't too sure what to do with the old lamp I picked up. To me, I thought that holding it up to the fire would cause it to light. I also couldn't find the second key to open the second door. I explored for a bit and didn't
find anything, I wasn't too sure what to do with rocks and old lamps.
Overall its very clean and very atmospheric. I couldn't make any of these models or make anything in 3D space that even comes close to this, so great job!
Small note -- consider supporting gamepad input if possible. I'm a normie gamer and prefer that to mouse/keyboard.
