Hoooooooooly shit I just got a PT Standard Unseen clear! I'm so frickin excited to have this off my chest! But now it's time for Advanced mode... :ohdear:
For a first clear, that was great. You were able to stay afloat really well in Unseens 1 and 3. I think you tried to focus a little too much on grazing in the early stage routes, but you were able to do really well with it in Unseen 3, so etc.
It looks like you don't have Unseen 2 or Unseen 3 unlocked for practice. If you like, I can help with that.
Zone Advanced has a lot of attacks that will nail you the first time simply because you don't see them coming. You may want to watch a video (or don't, if you enjoy that sort of thing). It is overall more difficult, though, so be prepared for that.
Also, are you a Vengeful Mad Scientist, a Maniacal Death Ray Wielder, or an Evolved Madman?
