Yea this game is quite challenging, I am planning to adjust the difficulty of this specific level when I start working on the update of this game. And about the spamming strat, I plan to add a miss counter and that would increase obviously, and I also plan to add a scoring system and that would also decrease when you spam.
But idk if I should count it as losing a life as well, since there 's also a spam part on this song (and maybe on other songs in the future) and I don't want the player to accidentally die on a part they should've actually spam lol. But anyways, thanks for playing and leaving a feedback! I appreciate it! :D
