This is amazing for a 48 hour game jam, really solid gameplay, combining the beats with the input seems to be quite hard to do and the polish in this is awesome, good job!
Thank you for your feedback! Actually we used Wwise to combing the beats with input, but I don't know the techincal detail because I am not the programmer of our team. But you can try wwise next time when you want to build a rhythm game. Glad you like it!
