Thanks for the feedback! Our main idea right now for adding a bit of a grace period is just to guarantee the first few notes are correct, so it'll be a bit more forgiving. Still want to do some more in-depth difficulty balancing, but we think it'll really help at least at the very beginning. With the notes being randomly generated, there's always a chance that the level skews difficulty, so we really want to improve this part of it.
Thanks for playing!
