Looks good and plays very well. Highscore does not Update and I would suggest it as the same problem I had on last jams: Your Highscoreservice has to be on a https connection if you host your game on itch.
I wanted to make Necromancer theme in the first place too, but beeing the artist this time and having a coder who has his first jam, it was to big as project. Good to see someone else did it nonetheless :)
