Thanks so much! Adding more juicy, satisfying visuals (like big rhythm games) is definitely on the to-do list when we have more time.
Yeah, agree with your theme comment. Initially, there were plans to have more of a "countdown" incorporated into the actual rhythm playing parts of the game. One idea was a countdown/slider which showed during the song, and the beats you played whenever the countdown hit 0 were additional points/added to combo etc. The decision in the end was that it added too much unnecessary complexity and that it was redundant with the normal gameplay of a rhythm game beat. There's probably some way we could have made an in between compromise to keep the theme stronger.
Thanks so much for your comment. Glad you enjoyed it!
