Great esthetics on this game, it's simple but elegant and well executed! The music gives a good atmosphere and I really liked the evil laugh that plays when you get hit by the big guy 😄
It's a very cool take on the theme too! Having your health represented as your source of light is a nice touch as well.
And it was nice to see the effort that was put into the accessibility settings! I did have a small issue in the main menu though, where pressing up on the keyboard would also act like pressing the highlighted button.
As a small nitpick, I think easy mode might be better suited to be the default mode, with hard mode being there for players that really got into the game.
Great job!
