There’s a good mood here. The lighting glare is especially nice. I think it might be a bit too dark around the player? I’ve made a game previously with moody lighting before and while I like it I wonder if sometimes you need to pop a light in the player so that their immediate area is a more clear. Or if not having a light maybe some more highlights just so you have some white/near white elements to balance the gloom.
Ok I double checked and there is a subtle light. I think youre onto something - but I also think its tricky to have something dark while still providing usable visible detail.
The foreground elements provide a cool parallax. I was wondering if the foreground beams would work better if they had some holes so they didnt totally block the view of the player - but also you do only put them where the player is walking - so maybe thats fine as is.
Anyhow in case it isnt clear I really liked it! You just wanted more feedback on the art so I just wanted to share some thoughts.
