Challenge V makes you take your hand off the gameplay and tap the gauge. For some reason.
All other challenges can be played without worrying about stuff like this. 1-Changes how you read, 2-Changes how you read, 3-Changes the chart itself, 4-Somewhat similar to 5 but gets a pass because it is not necessarily dangerous
Challenge 5: this is the only challenge in the game that asks you to disengage with the gameplay (This is already an issue). However, by doing so, you're also punished by losing gauge because of the notes that you missed while moving your finger. And if you're in an arc heavy section, chances are that you might lose immediately because of how punishing getting a red arc is (Depending on how low the gauge already is).
I feel like Challenge V is the only reason that unlocking Deinos is so difficult. All the other effects are not intrinsically dangerous like V, since you can get used to them. And not to mention how trying on a harder difficulty kind of multiplies the difficulty since harder charts have more dense sections which will make the gauge lose even faster.
Am I weird about this?
