Incredible art and sound here! I agree with lokko though that the lack of a visual indicator make it really difficult to play—even just being able to visualize each beat (note or not) would go a long way towards making it more playable. I'd love to play this again if you were to expand it in the future.
Also, full screen mode appears to bug out here—it shows the game over window at the top of the viewport if I switch into full screen. Will try to upload a screenshot here shortly!
