I love the dark and dreary vibe you got in the game, from the limited light sources you have and the music gives a sense of dreariness that fits with the environment. It really brought out the theme you are going for here! The controls I feel like could use some improvement. Movement feels too sluggish and slidey, like when starting and stopping the movement, in my opinion. I think having more initial speed on startup and more friction when stopping can help make the character feel less sluggish overall.
Regardless, I really love this concept and ambiance with your game! And congrats on completing your first game jam!
