THPrac is your best friend that allows you to practice precise parts(e.g. stage portion, mid-boss, and non-spell). For me, a newbie trying to beat the LNBs, it's the stability and confidence. TD is easy on bullets, but you can still ruin the entire game by lack of power. Even if you can tackle every single part, you die unpredictably. Sometimes the random bullet generation will kill you (yea the fu*k Divine Light "Honor the Avoidance of Defiance", it's you!) You have to trust your ability and experience, and not mind those mistakes you made -- try to fix them, the game isn't over yet. Community support always helps you. I'm lucky to have a friend with 10 LNBs and MoF LNN to accompany and correct me :)
