As the intro stage it is not exactly complicated but serves as a good introduction for what you will be doing all game if you want those sweet S+ ranks. Most of them are really tight as well without Lethal Lavaliere. The reason I choose not to use it (but i will be using other gear) is because it increases your score gain by 10% (20% if upgraded) at the cost of making spikes lethal, which is irrelevant seeing as getting hit at all will force you to reset the stage, deadly or not.
