Hello! :) Thank you very much for your detailed review of the game! I am not a professional Rhythm game player either, so I think the difficulty we managed to achieve for the game is enjoyable for everyone. Glad you liked and gave it a try!
About the synchronization of the beats: as we added the “hold the note” mechanic with few time to improve the songs in the last day, this was the best we achieved some hours before the submission ended :( but after the Jam, I will try to make the notes match better some instruments of each song, thanks for the recommendation!
Have a nice day as well! :)
