Did you try it on the WebGL or downloaded it? WebGL's got some known issue the game won't play right :/
Yeah, definitely would have put in a lot more player feedbacks if i had more time to polish it. Showing player if they were early or late needed to be one of them for sure. Other things like max combo # and a score at the end of the song (C, B, A, A+, S) would be nice too.
"makes we want to try my hand at a rhythm game too :D" I am so glad to hear that :)
Thanks so much for your kind words!
