I struggled with it at first and found the repeated voice lines a bit irritating (which tends to be an issue in most DR BTB/PTA sections). But after a while, I got used to it—using the slow-down mechanic really helped a lot. That said, I do think it would be great if there were an option to adjust the difficulty for players who find bullet hell mechanics more challenging (assuming that's not already the case—I only played on normal). One suggestion I’d add is an optional minigame that uses the same mechanics, similar to the arcade games in V3, so players can practice outside of class trials.
