time attack and sp points/blessings

[AreaQ]

First the time attack. Does this game time attack let you retry at each bosses? Just wondering because ys 1 and 2 doesn't and i can't see any other way to do this time attack mode on nightmare settings.
The blessing and sp point. I does it carry on when you do another play through with the same character or do you have to start from sctrach. It seems impossible to get all blessings in 1 play through without hours of fighting.

For Time Attack, the game will let you retry each boss if you need to.

For the SP/blessings, it resets every playthrough. However, upon beating the game, you are awarded an SP bonus for each level of difficulty cleared with each character (so the bonus can be as high as x 15). The bonus is initially 10,000 SP, but higher difficulties award less SP, so that figure gets cut depending on what difficulty you choose (I think you can have up to 150,000 extra SP on Very Easy, but only 1,500 on Nightmare).
