It's a good concept. I was getting some Darksouls vibes from it and the graphics are pretty good too. Unfortunately I could not pick up any notes or keys. I feel like with a little polish and some sound effects/music, this game could be great.
I'm actually an idiot and changed the 'interact' button on keyboard to be the down arrow, but didn't change the 'read note' prompt from 'Press F'. Sorry!
