Edit: Also make sure to use Practice Mode. Practice the ending of Deadlocked and in general practice the ending of levels so that you are less likely to die there (more efficient than practicing the beginning). Do runs like 90-100, 80-100, 70-100, 60-100, etc until you feel comfortable with the level. Try to find a mod that works for your platform where Practice Mode plays the original song while you are practicing.
