Yes I know that guide, I have read it and it still doesn't feel pleasant to play it or freestyle.
I'm not hating the game, I like the aesthetics, I like the songs, I like everything. But playing it just feels wrong. I understand that the game is inspired by parappa but it shouldn't feel just as inconsistent with the score and grades. I'm not a game developer either, maybe it's just my fault. But throughout my playthrough I kept feeling frustrated by the game taking away my score for a line that I felt I did well and I would just like to give this feedback from someone who really likes rhythm games.
