Good game. Some grammatical weirdness does exist but nothing too terrible. The more dark nature does also make this hard to play on monitors if the room they are in is bright. Some way to give the player a small outline or option to adjust the color would have been greatly appreciated. I also don't know if the hope being lost after dying is intentional or a bug.
Music is pretty good and feels well suited for the game. Some small sound effects would of been appreciated however. Movement and jumping feels right but sometimes I was sure I hit a jump but instead plummeted to my death, implementation of some coyote time would have been nice. The use of lighting was also very nice.
