Interesting take on the theme, I like the angle you took with diving into the 5 stages of grief. I especially like that the last stage, acceptance, has a very different way of beating it because it's about accepting what happened and healing/moving on from it. I found it to be pretty poetic in a way, so great job with the story!
I think the player moves pretty slowly and would've liked to move faster. Also, I think the description mentioned using the scroll wheel to switch weapons, but I totally forgot that mechanic; I think having something tell you that in the game itself would've been good. Though when I tried again, it didn't seem like the scroll wheel did anything.
Overall, very solid entry, and great take on the theme. Well done with this submission!
