Yeah, the memory dungeon is a huge pain and unlike the worm it comes around much more often.
Anyway, my last year's (or more precisely the last 6 months') accomplishments:
Story missions done.
Permanent and day of the week missions done.
Events 99-129 done.
Whaleship missions done.
Ultimate missions done.
Unique missions done, except for two ultimate unique missions: Scene 3 and Sage Laeva.
Cleaned out the Nidhoggr shop and got most of the other permanent items worth getting (except for whaleship and bond crystal shops).
Fully upgraded 3 knights (except for dressblooms, of course).
Status of remaining main quests:
player level quests -- 169/300 levels
aqua shadow quests (chapters 1-5): 43/125 clears
ultimate unique mission quests: 2/40 clears (only able to clear 2 of the 4 missions for now, though)
max affection: 107/300 girls
blossomed affection: 52/300 girls
garden picture book: 1501/1830 pest pictures
Still left to do:
Get superampules out of the bond crystal shop.
Get superampules and equipment out of the whaleship shop.
Get flower gems for events 1-98 and get Rainbow Rose and Asian Rice when they are added to permanent reprints.
Nushi missions.
Prison island.
Defeat the Scene 3 mission and the Sage Laeva mission.
Upgrade and evolve flower memories (the rainbow ones look like they will take a loooong time though).
Fully upgrade team 1 (weakness crit) and try to put together a decent team 2. No idea yet who will be in it, but probably will work towards counter crit (since I have Tarragon) or maybe try to get some sort of a re-act crit team with Silk Tree as the basis (and maybe Rrose, Balsam + some support for skill act and damage). Something with crit anyways, as it seems to be the only game in town. Here's my current lineup:
and best knights ordered by attack power, featuring the current MVP Sakura:
Edit: and with the newest addition:
