When you miss a note the game laggs and doesn
t register any inputs for 1/2 a second which makes it impossible to hit other adjacent notes, which isn
t a problem as long as you don`t miss.
But when the displayed scene changes the game laggs again, and if there are notes that you need when the scene changes, you just can`t.
And in a situation where you need to hit some notes during a scene change, you are unable to, which makes you miss a note, which makes the game lagg and not accept inputs, so, you miss a note because of the scene change, then you miss a note because of the miss-lagg and input rejection, and if there are more than six notes that you needed to hit in that time, then you instantly lose, without any way of passing the mod`s level
