Interesting idea and pretty visuals. Not particularly spooky though!

Fun game, it would've been nice to have some kind of score system to see how well you did.

Even if I'm not really good at rhythm games I enjoyed it quite a bit! If I can give you a little suggestion I think that adding a score counter would be cool and would help replayability :)

Nice game! The controls were smooth and responsive, and that's crucial for a rhythm game :)

I liked the idea of lighting the screen every time a note is executed correctly, it fits the theme. However, that's an evil decision for balancing: good players will see notes more clearly, having an easier game, while less-experienced players will have a harder and harder time. Was this "positive feedback" in mechanics intentional? I'm just asking for curiosity, there's not a wrong answer and no decision in inherently bad :)

Well... In my case I'm poor in rhythm games, so I enjoyed my little moment of despair :D

Lastly, I really liked the particle effects when the notes are pressed :)
