Neat concept! I included it in a compilation video series of all of the One Button Jam games, if you'd like to take a look! :)

It should be much more obvious now with the indicators, although you can't start your 4 beats whenever you want now so it's become harder at the same time.

Thanks for the feedback! Hope to add some flashing to the spell beats (the blue indicators). How it works currently is you tap the pattern and then at the end of the 4 beats you will see what you tapped out. Dark blue is on beat, light blue is off beat. I'm not sure yet but there could be some issues with the audio sync with certain browsers. I did create a little calibration section but it wasn't ready for release.

I think this is a really awesome idea! The only thing is I do not know the beat that I am tapping at. Some indicator showing your clicks would be great so that I know how to sync my rhythm to what the game wants.
